EVO as a USB Host?

Hey guys, i don't know if this has been addressed before or not. Is it possible to use the Evo as a USB Host, that is to say, (in my case) connect my DSLR to my Evo and download pictures so i can upload them to tumblr etc or flash drives to get files etc.
or am i just shooting in the dark here?

Possible (check)
Would help if you were well-versed in the art of Linux and mounting

indeed. but sadly, i am not. but! i am willing to donate to a helpful soul that is!

It's for the nexus on froyo but it could still work
If I had the right cable i'd test it for you.
This oughta work too

that looks like it'll work for keyboard or other INPUT devices, but would it work with external storage?

do you have a cable to even connect the two? micro to mini (if its a canon/nikon, if im not mistaken) micro to micro (pentax), beause else you'll need a powered hub according to the first link posted.

I just thought to start researching the status of otg usb and usb host mode on the evo. And to my surprise this is the only crappy thread I've come across. I cannot find an anwser as to if the evo has the hardware to support it. I know that the n1 droid and maybe the incredible support usb host mode even if u need a single its still something I want to know. I would drool over connecting usb flash drives, keyboards, game controllers etc to my evo. Someone else please show interest in this.

i concur. i'd love to be able to plug my ipod/DSLR/flash drive into my phone to upload/download files. i'd be willing to donate to make this happen

The list is endless... MIDI Controllers, extra screens, ethernet, fingerprint reader, wtvr.
Just got the cable today. Checking out these

...links and trying things now...
thanks for the pointers. I'm running cyanogen nightly 8-1... so far, i get:
D/Tethering( 102): interfaceAdded :usb0
from logcat when i plug my hacked (routed dc+ voltage from a nearby
+5v pin to the upstream cable red wire) powered usb hub into this OTG cable.
The EVO charges when i have it all plugged in as well...

Looks like they have this working on the Desire HD:

It's a similar device to the Evo, so maybe there is hope for the Evo to get it?

would like to bring this one back I just got a program called DSL controller it says my phone wont do usb host. Not sure if there is a kernel I need or if there is a ROM I can run etc.

I just ordered the cable I need for my phone and camera. So if anyone knows of a ROM that may do this please advise.

Any one try this yet? Do not want to spend the money till I see some one had it working

I too desperately wanted this to work... After buying the host-mode cable, trying various methods to allow "host-mode" on the evo, and trying a bazillion different combinations of settings - the DSLR controller software *always* gives me a "your device does not support USB host mode" error. I'm afraid this is dead in the water. DSLR Controller does, however, work nicely on my Asus Transformer tablet

USB Ethernet adapter for SGSII. Will it work (bridging)?

I get horrible cell service in my lecture class and poor Wi-Fi reception. All the rows in the lecture hall are outfitted with Ethernet jacks. If I buy a USB to Ethernet adapter would I need a special kernel to get it to work?
I saw this thread:
http://forum.xda-developers.com/showthread.php?t=1425178
This guy apparently makes a driver that works with the Rogue kernel for the Xoom. I have a Xoom also and I'm sure this works for it although I haven't tried it (I don't have the adapter).
Has anyone tried it? I wonder if it will allow for a bridge to be created to share the connection. I can only be signed into one session at a time and I wanted to somehow bridge it from my laptop to my phone so I can use GV for texting (It's that serious. I get A's though).
I hope I didn't confuse anyone reading. Thanks in advance.

USB Host Not Working

Hi guys. So the only thing I've done to my i747 is root it. I've tried both of the USB host apps in the market (USB Host Controller and StickMount) as well as the "SGS3-Easy-UMS" apk that's around, v1.2beta2 and v1.3beta. Can't attach any USB devices. All my flash drives are FAT32 and work well normally. I even ran the USB Host Diagnostics app and it confirmed that Android API, Rooted API, and Kernel "claim support" but no device is detected.
When I connect to sync, I can only do MTP transfers. This is why I looked into that EasyUMS apk because it apparently also allows to mount the phone on the PC as a USB Mass Storage device. During my search I see numerous people connecting flash drives, controllers, keyboards, and even a USB HDD to their sgs3's.
Because that apk requires busybox, and I have busybox, everything looked OK. However, I did once get an error from that APK about possible non-existant Kernel support. USB Host Diags disagree, as do many video tutorials.
Basically I'd like to know whether or not this is supposed to be working, and if not, then how do I go about making it work? I'd like to mount flash drives for easier use with Linux, and would like to mount the phone as UMS for the same reason. I would also like to use a USB Keyboard as well as a USB gamepad. Am I missing something? Are they all using the international?

Are you using a USB OTG cable?

got this one, a couple good reviews confirmed that it works with input devices: Amazon product# B005GI2VMG
i mean it's very possible that the seller just buys from random manufacturers without changing the listing. this one that i have is like the cheapest thing on the market so that may be the problem. i wouldn't mind trying a different one for <$5 w/ US shipping if that exists (recommendations?).

Same cable didn't work for me
I bought the same cable, but from a different seller. Amazon ID number B005N55WHI
And I have the same problem. Tried using it with several input devices and with several different roms and I couldn't make it work. Could it be a power issue? Does the USB device that it is being hooked up to have to be powered? I tried it with mice, keyboards, and flash drives, but all of those devices take their power from the bus, not an external source.

glad you posted. hmm. since we both have the same thing and they're both not working, i'm suspecting it's indeed the cable.
i read on a review of a different cable on Amazon where the guy cut open the connector and found no wire connected to one of the pins. i've had thinner-cable wires before that charged/transferred slower than others or didn't work at all on some higher-end devices, could really just be a cheap-out on the manufacturer's end.
i think i'd like to get a different cable. if anyone can recommend an inexpensive one that's confirmed working i'd appreciate it. so i don't have to shoot in the dark.

I got the one with Amazon ID B00871Q5PI and it worked for me. I tried a Dell USB keyboard, a USB mouse, and a USB DAC and they all worked. All take power from the bus.

got this one.... http://www.amazon.com/dp/B005GI2VMG/ref=pe_175190_21431760_M2T1_ST1_3p_dp_1
would it make a difference if it says its for the galaxy s2 and not the s3? im guessing thats why i cant get it to work.

No, would not make a difference. USB OTG is a standard and for now all devices that have USB OTG work with all USB OTG cables. I've used a cheapass one from Ebay with my S2/Note/S3 for more than a year now.

solved for me
so i got the one drothenberger got (actually that particular link was out of stock for the seller so i got the other suggested one that looks exactly the same, title OTG for SGS3 - item# B00871Q5PI) and i'm in business!!!
someone replied to my negative review of the other one i got in the comments and they said theirs worked. i think they just have different products under the same label or lots of defective ones. i'd recommend to just get the ones that specifically say OTG for SGS3 - the extra dollar or whatever is worth it to save the trouble.
thanks again to everyone for the troubleshooting, hope this topic helps others resolve their issues.

external usb hard drive possible???

My buddy is leaving for military overseas and just got kindle fire...not new one..he also got exteral hard drive. He wanted me to load up the hard drive with a bunch of movies i have for him to watch. Do i have to root the fire for it to read the hard drive? I have no problem rooting since i do it with all my phones and tablets. Ive seen stuff that involves having a OTG cable...im going to assume thats mandatory. What roms support the feature? Can you buy one of those cables at best buy or only online? Thanks for any help

I am not sure if this can be done, from what i have read a few topics on this in numerous places and nobody has had success with an actual external hard drive. Of course for it to even be possible you would need an adapter and there is still no way that i have found to make the Kindle to be able to read the content on the external drive to make it usable on the kindle. If it is i would also like to know how because the 6ish GB that are made available besides the cloud drive are quite small and can run low real fast.

Only one way to find out

I KNOW there is support for usb OTG for the kindle. What ROM to run? I have no idea. I know that you need at least Hashcode's 3.x kernel for it to work. twa_priv has a ROM that has that, is regularly updated, and has a lot of bonus features too http://forum.xda-developers.com/showthread.php?t=1778010. I a currently running it. I have an OTG cable, but I have lost all my usb drives. I have heard that it works with mice and keyboards, but haven't gotten any success with those.
I have this installed: https://play.google.com/store/apps/details?id=hu.sztupy.android.usbhostcontroller
i don't know if you need it or not, but i think you do.

[Q] Any way to connect the Galaxy Nexus to an Ethernet connection?

Hi guys.
I'm needing to connect my Gnex to the internet, on a wired-only network. Cellular data is not an option. Wifi is not an option. Bluetooth is not an option.
I've tried dabbling with reverse USB tethering - and it was working for a while - but now, for some reason, it's just not working reliably for me.
So I'm wondering if there's a working micro USB -> Ethernet adapter solution out there?
Do I need some OTG adapter and then an adapter like this connecting to it? Thanks if anyone knows what definitely works (hopefully from your own experience or knowledge of solid accounts of it!) - just don't want to waste money buying something that actually might not work.
My rooted gnex has CM11 stable 4.4.2 on it, if that helps.
Thanks

I bit the bullet and I can confirm, that it is working just fine, absolutely just fine!!! I'm so happy!!!
Even with Google Play Store, app updating is no problem! (it might be because I have the 'hack connectivity' app installed but I'm not sure...I don't think so...I think that only runs when doing reverse USB tethering, which I'm obviously not doing now...)
So, some information to report so it helps anyone else ever embarking on the same quest as me:
- If you're on stock Jelly Bean or above, drivers for some or most common Ethernet->USB adapters (such as the famous AX88772 chip), are ready to go, built-in. It will simply work right away, Internet working, plug and play Internet.
- But luckily, it works also with CM11 February 2014 build and up (and maybe much easier too, but my current build is a February installer build)! Hooray for that, no custom kernel hacking/driver installing needed!!
- Certainly one Ethernet adapter that now has multiple documented reports of success (at least with the gnex), is the Apple Ethernet->USB ('for Macbook Air') adapter. There's a youtube video here and a twitter post here. They're both with stock JB on the gnex, but mine is with CM 11 4.2.2. And yes, I decided to err on the side of superstition and got the same apple adapter, even if it was more than double the price of other perfectly great AX88772 adapters out there...hey, at least it works! And then as for OTG adapter, I just got a random $2 generic black one from ebay. Seems to be working fine, speed seems pretty ok, certainly faster than my WiFi used to be!
- Another bit of into: I read somewhere, that 'Make sure you plug everything into the adapter/OTG cable BEFORE plugging it into your [Android device]. While using a mouse/keyboard/hub I noticed if you plug the OTG cable in first and then a peripheral, the N7 won't recognize it.' But I can report, with the Apple Ethernet adapter, plugging it in after plugging the OTG cable in, works just fine . I just wait about 10-15 seconds to make sure it gets DHCP and away we go .
Hope this helps someone out there, thanks for listening!
