Is It Possible To Use USB Devices with the Kindle Fire?

I got a little micro usb to usb adapter for a buck and I've tried connected a few flash drives and a keyboard to it but nothing seems to happen.
Is there anyway to get usb devices to work with the kindle or no?

Yes, there are certain USB devices that work great with the Kindle Fire. First thing is, the device must be rooted and running a custom ROM. A recent JB ROM will do just nicely and CM7 on the Kindle DOES NOT SUPPORT OTG.
I successfully use a Logitech k120 keyboard without any problems. Usually as soon as I plug it in, the Kindle will recognize it and then it's useable. The keyboard DOES NOT require a powered USB hub. I also can use a USB optical mouse but a powered USB hub IS REQUIRED for that as the Kindle does not have enough power output from its micro-USB port.
I haven't really tried to mount a flash drive yet but some do require a powered hub and others do not.
Are you using an actual OTG adapter? I bought one off an online auction site for $2 and it was labeled for "Samsung" devices but that doesn't matter.

Thanks for your reply.
This is the adapter I bought:

Did I get the wrong one?
Is there a notification to let you know it recognized a device? Anything in the settings I have to change?

That's the same one I bought. On the 4.2.2 ROM I run, as soon as I plug in the keyboard to the adapter some notification DOES come up but I can't remember what it says lol. If I try to plug in the USB optical mouse WITHOUT a powered hub, the mouse lights up indeed but that's all it does. It does not function other than lighting up.
I'm currently typing this on CM7 as my Kindle is set up to dual boot. Some keyboards are not compatible at all, I couldn't tell you which ones exactely but I remember seeing that stated somewhere down the line.
In reference to the Settings, there is nothing I had to change keyboard wise to get it to function. There are simple options for the mouse cursor like speed. The flash drive is a different story and many people have had to use apps like Stickmount and such to get them to work. Unfortunately flash drives are hit or miss and a couple different approaches have been used to mount them.
Hope that helps

ion dk20 dock vs jelly bean

I was wondering if any of you have the same problem as me.
Just bought the dk20 ion dock and pluged my ion jelly bean to it and:
- first nothing happens wen pluging it in, if mouse and power cord connected it charges and cursor appears.
- doesnt autodetect dock
- hdmi (for me most important) does not work..
- pendrives and/or flashdrives are detected ok
so the dock is as for now a nice charger and that is about it!
let me know if any of you are having the same issues, and lets see if wll together we can do something about it.

I have had zero issues with mine. USB capability seems to be hit and miss. My cheap mouse and old Logitech keyboard work fine. I could not get a Logitech k400 to work though. As for getting hdmi to work make sure the cord is plugged in and tv on. Device screen should be off while plugging it in. Once in turn on, unlock, and it should show up. Then you can pull the notifications down and hit tv launcher. You can also set it with smart connect to auto launch.

Are you using Jelly Bean on your Ion as me?
I have followed your steps and nothing, pluged the HDMI cable into the dock and turned the TV on with the HDMI 1 channel on, with phone screen off connected it (with only the HDMI cable plugged in) and nothing happens. If I use Smart Connect App, when choosing dock it does detect the dock, but the TV mode does absolutely nothing.
Im beggining to think it could be the HDMI port on my Dock that doesn't work properly, I did buy it on ebay.. so you never know!
Let me know what you think, the whole idea was using my Ion as an additional basic PC, but without hdmi it's not going to be to useful..

Yes I am running the Rogers jelly Bean. It is very easy to disturb the hdmi connection when you mess with the dock. I am using a hdmi to micro hdmi adapter. I plug my phone in then hit the power button and unlock it. It then recognizes and shows on the tv. If you pull down the notifications you have options for tv launcher and also hdmi settings.
One thing you can try is connect the hdmi to your device directly and see if it works.

I think it's the HDMI port on my dock then, because it just doesn't even notice the HDMI connection, I'm using the cable that came with the phone, I have a factory unlocked lt28h Ion that came with all the extras, hdmi micro to hdmi cable and smart tags..
I may try doing a downgrade to see if it works ok on the ICS, I have read it had less problems with that version of Android.
Once again thanks ever so much for your help and interested, ill keep the post updated just in case other people are having the same problem as me.
Pd: The HDMI port on my device works fine directly to TV, the only thing is I have to adjust the screen dimensions to 95% now I'm on Jelly Bean so the picture is ok on the TV.
Regards, judgefargo

Finally the new Dock arrived yesterday and guess what.. It works like a charm!!!
So in the end the problem was a faulty HDMI port, the seller was kind enough to send a new one for free.
Thank you all for your help, as compensation ill leave a few discoveries I have made so you can use your ion as a spare PC.
For ROOTED devices i strongly recommend Screen Standby App, that lets you turn the screen of whilst the phone is docket and uses 1/3 of the battery, as well as not bothering you whilst watching a film or other tasks.. it has many other functions to.
Another great app is Paragon, which lets you connect external usb and hard drives in any format, specially NTFS, please note that for usb and hard drives to work the power cord has to be connected, due to the drain of power, as device warns.
That's it for now, hope this info is useful for other Dock owners and users!

Awesome I will try this out. Glad you got a good dock to work with. If you come up with other interesting stuff let us know.

NTFS is standard format for Windows and for it to work in Android it needs to be fat32 format. Don't think there is much of a difference other than just the type of format. So you would right click your drive you want to use and format it as fat32. Then put what you want to on it and plug it into the dock. The phone should be able to see it at that point but you will need a file browser to access the drive. I will try it in a bit to confirm it works but from what I have read on the Z forum it should work fine.

Can I change the format without literally format my ext HDD?
XDAプレミアムを使 用して私のSK17iのか ら送られてきた

No. You will have to backup or move what is on the drive and do a format. Formatting wipes the drive and no way around that I know of.

The problem is Android is not programmed to read NTFS format which is a windows format.
But if you install PARAGON app it makes the OS able to read NTFS drives without having to format your hard drive to fat32.
I also have a WD 500GB Hard Drive and faced the same problem, there is other programs but paragon seems to be the one that works best.
Hope that helps, regards and good fortune!

USB OTG - external devices not recognised

Hi there,
I have a game that I wanted to play with an external controller, I've got a wired XBox 360 controller to hand, so I went down to my local computer shop and managed to get my hands on a usb otg adapter.
I was using a custom rom based on 4.2.2. When I plugged the controller in it gets power and the central light blinks. However, the system gives no message telling me what it is, and the controls do not work for the game.
I tried the USB host controller app and that told me "usb s3c driver not found", or something similar. It also did briefly tell me that the 360 device was connected.
I thought perhaps if I tried a different rom with a different kernel that might kick things into life. So last night I successfully installed the JazzRom from the development page for the Galaxy Note 8.0.
After that, I plugged in a mouse - which, low and behold, it recognized - I saw the cursor moving over the screen and everything! It did seem a bit dodgy though, in that it would say "mouse disconnected" when I hadn't, then I would plug it back in and it would connect again. My USB keyboard worked too.
Then I tried the XBox 360 controller and nothing happened.
I've tried various apps to diagnose the problem - but if the system doesn't pick up the device when you plug it in, it doesn't seem there's much you can do. What's more annoying, now the mouse and keyboard don't work either.
Is there nothing I can reset or alter (I have root access) to help? I've tried the cache in Settings and wiping the Dalvik cache. I have a app called USB/BT Joystick center now, that might help if it could get a signal from the controller, because somebody said it might just be the mapping of the XBox controller that stopped it working.
The only other thing I can think of is maybe a dicey otg cable.
Surely this should work, in theory, though?

Carperformance.se Uconnect Android system help.

I am hoping I can find some help in here with a couple problems I am running into on this system that would make it so much better to me.
The system is basically an Android box utilizing the touch screen and monitor of my Uconnect 8.4 head unit. The naming in the settings is rk3188 and is running on KitKat 4.4.4, so it is some variant of the Android TV boxes. If there are other specs or info that are needed to help in possibly fixing my issues please let me know.
Issue 1: although not major, there is no option to have OK Google from any screen. Having this option for a car system is obviously something helpful. In the settings of the Google App trying to access the menu for OK Google detection doesn't work, so I can't even get to the screen where that option lives. I have the most up to date version of Google App and Google Play Services. I have Google searched on ways to fix this but nothing has brought that ability up. I know Android version 4.4.4 was capable of this. There was another app that utilized Googles voice engine and allowed this function but Google made him stop using their servers and killed that as an option.
Issue 2: this is the biggest bother to me and I could not find anything even related to what's happening in my searches. The system comes loaded with some apps and using Launcher3 for its front end, it has big buttons but offers almost no ability to customize it. The bottom row has apps that you cannot switch out to anything else, and 3 of them I will never be using. The system works but is not as nice as it could look or function. The obvious answer is to use a different launcher which is where the problem arises. I have tried to use Nova and Apex so far with the same very frustrating outcome. After the install everything is great, I can set the screen up to look amazing and add icons and functionality that really make it a great experience. So everything is working lovely then I shut my truck off and go do whatever. The next time I come back I start the truck up everything loads fine, the new launcher and everything I did to it is working just as expected until about 5 minutes in the screen goes black for a second and then the system goes through a factory reset. Really? Are you kidding me? The first couple times I thought maybe I hit something because I hadn't fully put my truck back together but after playing with it more and having the system factory reset 5 other times I have concluded it is related to changing the launcher. I tried Nova first, then I tried Apex with the same outcome and same sequence of events. Obviously it's annoying everytime testing this because updating and reentering my info everytime just to try the launcher again is time consuming. The last test the only thing I did was a different launcher so that has to be it, but why and how can I fix it?
If anyone has any clue how using a different launcher would cause a factory reset to happen please help me out. Or if there is anything I can do to this system to prevent that. My last resort thought would be to root it but I read someone else who has this system that rooting it caused screen layout issues and made things go 90 degrees off? The loaded apps in the system have touch screen calibration and screen resizing which might be necessary for this to function with the monitor.
Thanks for any help.

I spoke with someone else that has the system and they are not having any issues with running a different launcher so something happen to my particular device. I contacted the company and they will be getting me the firmware to refresh it and hopefully that fixes the resetting issue.

i am looking to get this also. I am very curious how you like the device - it looks great though a bit out of date. Waze & email should work well. How much storage does it have? Can you add a sd card or something?

I'm getting a new unit sent out, it seems there are 2 versions and for whatever reason mine wouldn't let me customize the launcher.
But even though it's outdated, every app I tried worked just fine, they still install the latest versions. The system has 8gb of on board storage and a microSD card slot that is mainly for loading maps for offline navigation. I think you can still access it for other uses, but they have a better option for that. There is a USB input for flash drives or external drives. I tried my 2TB external drive on it and it accessed my movies fine from it.

How did you get it installed? Who?

got any pics?

Actually I would be interested in this too, I have an Alfa Romeo and the Uconnect 6.5 (european version) which isn't that great, it would be nice to attach a sort of box with ARM hardware running on Android and using the display and touch of the existing Uconnect. The question is, how this can be done?

I would check out this thread. It has two videos that walk you through the entire process - great info!

I also bought this latest Android system V4 2 weeks ago. Auto launcher pro app is very good working. At the moment there is a issue with the system time, which is not correctly synchronized with gps time. Carperformance Team is working on a fix for that. How can I get root Access for this Android 7 System?

glad to hear i'm not going crazy with the clock but there is an issue.
I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

Hi @michaelk
Good to hear that I am not alone here with this special system V4. Except for the issue with the system time and no root access, I am fully satisfied so far. I hope to fix it soon. If we had root access then we could solve this issue with the system time with some time apps ourselves.
Thank you for your experiences.

wiring harness investigation
so played around some today.
I've got an issue where I need to recalibrate the screen almost every time I boot. it seems the box (or card added to the radio?) forgets things and only works the bottom right corner and also seems to rotate 90 degrees at boot. The end result is unusable screen. I think carperformance is just a reseller because of their response. They're friendly and reply quickly but are really unable to help. The first answer was just randomly fiddle with screen and try to find calibrate setting and reboot- that proved impossible and on my own I discovered a 6 dollar USB mouse from the Walmart could be used to navigate to the calibrate app. When I inquired again when it got more frequent they basically said it's not normal and offered no help except to adjust a personalization setting to run calibrate on boot- that only works once that I can figure (might be related to weird time bug)- so I settled on having tasker run calibrate on each boot. I wonder if there is a battery in the box that needs changing but the warranty sticker keeps me out for not- might add an external battery to keep it alive for a longer time to minimize the rebooting
Anyway took everything apart today to double-check and can't find any connection issues. I traced the harness a bit to try and understand a little and basically, the skinny cables run the daughterboard to snag the screen output and the touchscreen input. But i wanted to figure out what is tapped from the radio harness to the large white plug on the box and see if anything going on their .
DISCLAIMER- I NEED TO CONFIRM (it was hot - laughing) but basically seems what is tapped in radio harness is:
1) power and ground also
2) L&R aux audio signal- interesting here is they tapped a single ground (physically next to the right signal) for common. Earlier i had the RAX hack and their harness used a ground for each L&R and their aux input worked all the time without the little plugin shunt thing to trick aux input. When i dug some more and found a pin diagram from mopar I found that the 'left' ground is actually labeled "aux audio device detect signal" I need to play some more to see what happens but my guess is if we put a switch on that to short it to ground then the aux would just work to avoid the hokey plug.
3) Here's the fun- holding the screen to flip inputs could be the daughterboard running things. BUT since it also reacts to the left steering wheel button pack and switches inputs itself when you need the reverse cam- i figured it reads the can bus. and sure enough, it looks like it taps CAN IHS (+) and CAN IHS (-). Very cool that it would get into the whole bus and read anything- BUT since there are other FCA vehicles that don't auto-switch inputs on revers and they have alternate connections it seems the real dev is not involved to update things to sniff for other reverse signals. Reading around here- seems that there is probably a custom serial port someplace in the box that reads this and there's probably no documentation for us to do anything ourselves. But one can hope...

So the spec for the chipset for the V4 says it can handle an OTG port and a couple (maybe 3?) other USB ports. Obviously, the box only has the one USB A port visible on the pigtail. I wish we could get in the box and look for a header for the OTG port to help rooting but.... the darn warranty sticker.
on the FCA/Dodge side of things- I have a Durango with a USB port and SD card reader in the dash (USB Media "Hub" Apparently, FCA uses USB Mini B connectors to interconnect all the ports and the radio. They use latching connectors that are keyed but if you undo them there's a standard USB mini B in there. They do some odd male/female things so you have to pay attention to where you undo cables, but bottom line you can undo the connector on the back of the dash's USB port and stuff a USB mini B female on it and connect it to whatever host device you want.
I first tried an old laptop in case there's anything weird going on. My Dash "Hub" actually has 2 mini-B connectors and a multipin auto harness. Without the harness when you connect it to windows it sees a USB Hub, but the USB port was still dead. So I assumed it needs power from the harness on the back of the dash hub and connected that. UP popped up a USB mass storage device which I believe is the SD card reader- didn't get around to confirming and then the USB port also comes to life. Knowing that it was safe at that point I connected it to the USB A Host port on the box and presto chango now I have the in-dash port connected to the android tv box without any exposed wiring.
Connected the "android auto dongle" through the cars USB port and that works perfectly. I ordered a used 2 USB dash hub from eBay (later model years have 2 and will see what that does. The pictures of that also show the 2 mini B ports- I'll play some more when I get that. I'm not sure what is in those dongles but from the other folks hacking android auto into older models (by using newer radios) apparently, one port works for android auto and the other doesn't. The scuttle is its a body module programming thing but I wonder if maybe there's something physical in there and so the dongle won't be necessary any longer with the new hub? My other thought is if the two USB min B jacks allow you to connect to 2 different hosts- I would try one on the original Uconnect (in case I ever need to update the software) and the other for the android TV box.
So apparently the android tv box handles hubs just fine. As I mentioned earlier it handles a mouse or USB keyboard fine. Also, I played around and connected my hotspot by USB instead of wifi so the device sees it as a modem and that works just fine- so I assume a USB modem works out of the box too. (again odd if that works that carperformance sells a hotspot and not USB modem- like they don't know what the box can do)

I disassembled my display 2 times until it worked. After the first start, I had a black screen. I thought that was it... After 3 times it finally worked. I also had a cable on the plug which has easily resolved. I think you will also have a loose contact somewhere. One time I also had the display calibration gone. Then I connected my old usb keyboard and could then start the display calibration. I reset the system before. So far, the system works without problems. I also have a passive 4-way usb hub to connect.
I have already connected cables for the frontcam but have not yet moved into the engine compartment.
In the video tutorial of Carperformance, you can see when you switch to drive, the display then changes to the frontcam or signal from the cam, but the display does not change to the Frontcam signal with me.
Do you have with you the signal on the display of the camera when switching to drive?

Adw2 = bad mix
Went back and forth many times in email and turns out my calibration issue was probably all ADW2 launcher, guess it conflicts with whatever app they use to communicate with the display.
in the process of troubleshooting I got the update zip for the current version but I don't think those have recovery partition in there and so can't help root? I need to read some more.
I've ripped everything apart like 12 times with the screen, so that my front cam is not connected right now. For the brief time I had it, it was connected to one of the smaller video in pin connectors and don't think it worked in drive by itself, but can't really say for certain. I think certain models can't get the canbus command to see reverse and if I understand they connect in to the video in on the main connector and then use a point on the car that is energized to trigger the switch on that connection. If your adventurous they seem to have to flip a dip also. I think it's the Cherokees or maybe grand Cherokee so maybe Google their thread's? This site gives connector pin outs
http://connectors.dcctools.com/home.htm
There might be a lead for the drive on your shifter if lucky. I think I read the reverse shoulder comes from a body control box in the passenger wheel well?
Also they're super friendly and never wrong when you email but they can be brief. So you could ask if there's a dipswitch to flip to enable auto switching one of the inputs. Hec maybe we should just ask for a table of where the dips do...
(Sorry for any typos... Will try to edit later)

Supposedly it is enough to connect the extra input cable for DVD or CMMB. That answered me Carperformance. Before, I had no external input cable connected. That's why no signal came. The OEM rearcam works flawlessly.

Also, I forgot, they have a workaround for the clock bug
For the clock there is a fix

It's a cheaper fix but so no solution. Carperformance should offer a software update with root access. Then we would be satisfied. We should expect it for the money.
My frontcam is working now good.
You already tried Android auto? Which USB dongle do you use? Do you need a special app for this?
My China usb dongle does not want to connect properly with my oneplus 6T.
Edit:
Android auto is working with Pumpkin USB dongle and autoplaybox app. The noname China scrap goes back to shop.
The time fix is working until now also. Thanks for this info. The carperformance, they wrote or informed the affected people who ordered it. I did not get any info.

besides powering your camera and connecting the yellow RCA video signal did you have to do anything else?
something with the red signal wire maybe?
I cant consistently get a signal on my front cam and not sure if the camera is bad or my setup

few other notes for others-
FCA "aux audio device detect signal" harness line is actually normally closed (I think shorted to ground)- if you break the connection the oew radio flips right to aux in. make the connection again and it flips back to previous input.
the in dash usb port is infact a powered hub. I originally had a usb + SD card combo and replaced it with 2 usb port and works fine. FCA uses mini b connections to it- just use a usb a to mini b cable to connect it to the android auto box and your indash usb port(s) will work on android auto (And provide more watts to charge your stuff). oddly either dahs hub has a second usb mini b connector that i played around with a little but never could figure out what it does
more can bus fun! - i updated the dongle firmware on the android auto dongle sold direct from carperforance and now it has a beta feature to map buttons. somehow it seems to be sniffing the canbus through the android tv box. it has arrow keys, numbers, enter, etc and you use the app to select the input to assign then you press the same button on the car twice- it sniffs the signal and assignes it. I My durango has the button packs on the steering wheel and i was able to assign up, down, left, right and get it to have the android auto respond. Need to play more but i think it actually goes android wide. For example i think the down button on my steering wheel was sending page down to the chrome browser i had open on the box. Pretty cool stuff if they expand that.

Question S22 OTG Gamepad Gamesir x2

I have an S22 with Stock Android and bought Gamesir X2 to play XBOX Cloud and Retroarch games with it.
For some reason I decided to buy the USB-C version over the Bluetooth (I thought I was neat to be able to charge the phone while playing and also less input lag due to BT delays).
Thing is, gamepad arrived, I rushed to plug it in and found out nothing happened. Gamepad blue light stays blinking (its supposed to stay blu when connected) and the phone doesnt even detects anything.
This is supposed to be a simple OTG gamepad, so should be plug-n-play.
I reached to Samsung about 'how do I enable OTG to use my gamepad' and the answer was 'OTG is enabled by default'
I also reached out to Gamesir, they told me to try press G+S buttons on the pad while connected, but nothing happened
There's a Gamesir app that is suppsed to be used to detect it (and also map the gamepad on some touch screen games) but doesnt work for me
I also found some guy on youtube claiming I should enable ADB debug and set USB default to 'File transfer'. Doesnt work either
Anyone having the same issue?
Anyone having a USB-C Gamepad working?
Any ideas on what to try out to get it working?
Thanks in advance

I've recently run into a similar issue however on a S23+. The device I'm trying to use is a Seek CompactPro FF USB-C which uses powered OTG. No need of a cable as it has USB-C built into the device itself.
It didn't work at first, it detected it and tried to open the "Seek Thermal" app which is normal but in the app itself the device was not being detected. Did a ton of searching until finally I found another person having a similar issue where the work around was to plug in the OTG device, then reboot the phone with the device still plugged in.
Give that a try? IMO it shouldn't be like this, and it isn't very well documented anywhere I look...but that worked for me for my device. Did not work any other way. Device works perfectly fine after rebooting phone with it plugged in.

Thanks for your reply 86, tried that but didnt work for me. I saw a couple of videos where the blinking blue light might mean that its not connecting well (its supposed to stay blue) so I guess its something to do with how the cable is connecting. Since Gamesir already told me I have no warranty nor support from them as I bought it on Amazon instead of their site I'm thinking on tearing it appart during the weekend.
If I break it I'll end up with a nice pouch case for my cables (the most expensive pouch ever).
