USB Adapter with a USB hub

Hello all,
I received my USB adapter from Samsung today and am pleased to inform you that it works wonderfully with a USB hub. My hub has 4 slots on it and the tab was playing well with multiple USB devices being plugged in.

Really? I guess usb hub is needed to make things work? i had all kinds of issues. Mainly, not reading some usb drives, and memory reader. I just plugged the usb drive, directly into the usb adapter. The memory card reader was connected by standard usb to mini usb cable. That didn't work.
I got to try this.
Thanks.

No problem. I actually have not tried storage devices yet, only input devices. I posted on your other thread as well.
I have a feeling thumb drives may be having a problem if they are formatted in the FAT32 file system. I am going to try an NTFS drive and external hard drive and will let you know my results.
UPDATE: It appears I had it the other way around. I plugged in an NTFS drive to no avail, then formatted it to FAT32 and it worked.

FAT32 works great. NTFS is completely missing from stock kernels, it's in pershoot's "lib" extra modules archive on his kernels. However, I tried an NTFS drive using the extra module and it failed. (might require some manual mount magic???) It would take a lot more work to get FUSE working properly, and that's needed for the (vastly superior) ntfs-3g driver.

So does it work with external usb hard drives (both self powered and plug powered) of the sizes of 500GB and more?

what brand/type
what brand/type of usb hub do you have

If the hub is powered then the drive should work fine. You just can't use a usb powered drive without a power source

Ican't get mine to read my game controllers. Says something about high powered device. It won't let me read the message. When I tap it to make it bigger it just goes away. I am very frustrated. Can you get a fame controller to work? I used ps3.

PS3 controllers require a special driver. It may also require too much current since it tries to charge via USB. You'll need a powered hub if that is the case.
Gonna try my PS3 controller in a few minutes.
Edit: So far:
No excessive current errors from my PS3 controller - however mine has a fully charged battery because it's been plugged into a PS3 that has only been playing movies/videos for weeks. However button presses aren't recognized by anything. My guess is that if I dmesg I'll get an unrecognized device error. PS3 controllers are nonstandard.
However a Nyko AirFlo controller worked fine in SNES9x EX. It was semi-recognized by SNESoid - the keymap screen recognized something was being pressed, but games themselves wouldn't register presses.
Edit 2: PS3 controllers require the hid-sony kernel module to be loaded. This is included in pershoot's optional "lib" archive with his kernels. I had to hit the PS button to get it to turn on and start sending presses to the tab. No excessive current errors, but my controller was fully charged.

Thanks. But for some reason the ps3 and the x box controller worked for the xoom. I called samsung and they don't have any help for this issue yet. Can you get any external device to work for at least over fifty percent of what the adapter is meant to do? Did you get any error messages. I get high powered device connected. Then it say underneath that out could not connect. Device needs............. I cant read the rest. When I tap it to enlarge and read it disappears. Samsung can't figure out why that is happening either. Plz help.

Make sure the PS3 controller is fully charged before you connect it. If it isn't, it'll try to charge the battery and that's probably what sets off the overcurrent protection.
As to it working with the Xoom - I'd be VERY surprised if it worked with the Xoom when stock. Not so surprised about custom kernels, adding those modules is one of the first things people add, and the Xoom guys may have figured out module autoloading.

Thanks going to try now

wish i'd have read this before i bought it. i assumed it would since every other android tablet i have/had can power my external hds. pretty much makes it useless for me now as i was hoping to use it as external storage and for easy, quick file transfers. tf, xoom, and archos all work fine.

It works on a stock 3.1 build, it was one of those new features hyped at google i/o. I have both the European XOom and the Galaxy tab. The xoom copes fine with the ps3 and my other usb only non brand gamepad. The galaxy tab give me the hipower usb device error.

For SNESoid, you probably forgot to go into the other settings menu and turn on external input. The names may be off, but in addition to setting the key mappings, you have to turn on another option for it to see additional input devices, and then your gamepad will work

I had troubles reading an SD card with an old USB reader I had lying around. It was hit and miss.
Then I bought this SD card reader at Fry's for $4.99 and it works perfectly.

So, just to be clear, you are using a male A-A USB cable with one end plugged into the USB adapter on the GTab and the other end into one of the available USB ports in the hub, right?

[Q] Galaxy 10.1 USB connection kit problem, USB sticks

I've got an GT-P7500, and it will not read any USB Sticks.
Using the Samsung connection kit.
tried with 15 different USB sticks, all FAT32 formatted, all sizes 1-16gb.
A friend uses a 4gb stick in a GT-P7510, i tested that one, didn't work
Other things like usb mouse works, but not usb stick.
Anyone got any suggestions ?
Wonder if there is something wrong with it.

How do you know it isn't working? What directory are you looking at? What does the notification bar show? Which connector are you using? Is USB debugging on?
Also this is more a Q/A...

I'm hoping this thread is still alive because I am having the same problem. @ajnindlo I'm using the standard Samsung USB Connector with a 8gb usb stick. I've tried with USB Debugging on & off and I get the same message. "Damaged USB" and asked me to reformat.
I am using a Mac BUT I did format the stick as a ms-dos fat format.
Please help...
Thank you
PS. I know this is more of a q&a place, didn't know where else to post and didn't find any other with this problem but here. Please redirect to correct location if you know of a solution. Thank you

Just i hace received my USB kit and it works perfectly, my USB has 16 g and i haven't do anything to work, conected and work.

I had a 32 GB sd card and it also wouldn't be detected by my Galaxy Tab. But, I plugged it into my phone, plugged my phone into the computer, formatted the sd card and when I put in my Gtab, it worked.

I got my connection kit today but its not working at all.
Got 2 adaptors 1 for sd card and 1 for usb connection they both dont work.
Got no status bar message or anything.
Do I miss something here?

one catch that I have realized is that for proper identification of the USB Stick, the tablet must be in english language.
My friend had a hard time figuring out why his tablet won't show up any notification when a USB Stick was connected, whereas mine shows the "My Files" app showing the storage folder and all the contents of the stick, joking around I told him that was because my tablet was in english and his tablet was not.
Anyway, Astro file explorer doesn't work with USB Sticks, Use ES File Explorer instead and look in /mnt/ folder for usbdrive , there should be your content.

Nope still not working. No files found.
Feels like my device doesnt support usb host.
Is that possible?

Connect the usb stick, open ES File explorer and go to /mnt/usbdrive folder, if you can't find the folder (which is not on the sdcard) you need to configure ES File explorer to get out of the sdcard directory, the usbdrive folder is always present even if you don't have any usb drive connected

I had similiar problems with my 16GB P7510. It would only recognize any of my Sandisk sticks and a brand new PNY only at 30% of the time. The only stick it was reliable with was an ancient 256MB stick I had. I worked fine with my camera.
I ended up returning it for a 32GB P7510 and have not had any problems with any of the sticks. At the time I didn't think the tablet was defective but it appears it was.

I have exact the same issue, but it's strange, some SD has this issue, some don't.
"Damaged USB"
I found a trick, but it solved my problem only once: format SD card by a digital camera (Canon powershot) , SD was now recognized by Tab10.1
Putting some extra files on it by PC ... insert SD to Tab10.1 ... same issue again :crying:
Have tried several SD formats & sizes ... notting helps
Did someone knows a solution to solve this problem

Correct ... but after a second or third time connecting same SD , issue returns
Have tried this, waiting for a while does helps time to time ... so I guess it's maybe "memory" or "kernel" (system) related.
It seems we have the same TASK14 ROM + Pershoot's kernel.
Strange things.

I made the test by unroot my device and went back to factory stock ... it look like the issue is solved for 90% ... it appears when you disconnect and reconnect to fast after the 1st disconnection .

usb not recognised
Nothing happens when i plug (several) usb sticks. /mnt/usbdrive is empty.
Any idea?

charging Problem
You must Check that Your usb Debugging is On or Not as it creates problems and this will be stopping You device from Accepting Usb Sticks..

I found that FAT 'sdCard's would mount , but that NONE of my NTFS sticks would mount
All my sticks are NTFS , so that was unacceptable.
rooted 7500 and 6800
Installed 'Paragon NTFS&FHS', from the AndroidMarket and all files now popup in 'MyFiles' when I insert the usb with the adaptor

I have the Samsung Connection Kit containing as USB and a SD adapter. The USB adapter works fine, but the SD adapter doesn't work at all. All it does is starting the TuneIn Radio app when it is connected. I uninstalled the app and now connecting the adapter has no effect at all. Any suggestions?

USB OTG issues

I have a tmobile sgs3 with a stock rom (it was rooted, but latest update seems to have killed that), and after seeing the androidNZ connectivity demo I decided to play around with the usb otg. I am having some problems however. I have tried with 2 external hdds and a thumb drive and all three light up, but do nothing to the phone. I get no pop ups, and when I use astro to check the external usb drives, they all show up empty.
What am I missing?
Thank you!

I do not have that issue, but did you check USB debugging mode in Developer options?
I haven't tried to connect to an external HD, but USB Flash card works fine, as well as USB keyboard & mouse.

I've bought a $2 USB adapter for my phone and I have been able to mount a pendrive or a HD (when it is plugged to an external power source).
But when I try to connect a Mouse, Keyboard, Gamepad, etc., nothing happens. Not even an error message.
I'm using an official Android 4.03 rooted ROM (Claro Argentina).
Does anyone know what could be happening? The problem is my ROM (and it's drivers)? Is my USB otg adapter that is not compatible with mouse and keyboard?
I attach a screenshot of my system

[Q] USB connection problem

I've got a new Nexus 7 (2013) that I'm trying to connect to my 128gb PNY USB 2.0 Flash Drive(formatted NTFS). My device is rooted and I've tried multiple USB hosting apps such as Nexus Media Importer, OTG helper, and Stickmount but none of these have been able to recognize this drive. I have another old 1gb Cruzer that I have no troubles using and the 128gb PNY Drive works fine on my desktop. This makes me think the Nexus 7 simply cant power the Flash Drive however I have read others claiming they are able to power some larger Flash Drives and mid-sized external Hard Drives with much more space so I find it hard to believe I just managed to find the wrong brand drive. Sometimes the Flash Drive seems to get detected for a split second but before I am able to even finish connecting it is lost again. OTG Troubleshooter sometimes will not detect any device, other times it will detect the device for a quick moment and give issue #58277 yet other times it will pass the troubleshooting test and send me to connect to the device but by the time i get there it has disappeared. Any information on what may be causing this issue or what Flash Drives the Nexus 7 is capable of powering would be greatly appreciated.
Thank you,
Jake

Try Paragon NTFS to set SELinux to permissible. I use both that app and Stickmount for my 64gb Sandisk Dual USB.

Paragon NTFS can't pick up the device either. I can only ever seem to get the device detected for a brief moment right after plugging it in so I guess its a power problem. I just don't see why this flash drive would take so much power. If anyone can confirm some higher capacity drives that work with the Nexus 7 that would be great.

Hi, were you able to solve this problem? I also have the same issue with this USB device. It seems to work fine on my Samsung S5, but not the nexus7 or S3.

OTG not working

So Ive run into a strange problem. I was watching a movie last night on my nexus, the file was on my usb drive connected via otg to the nexus. Today I try to do the same and I get no reaction from Stickmount when plugging in the drive. I have no problems charging or connecting the tablet to my PC, and the drive works fine both connecting to the PC and to my smartphone with stickmount as well. I also tried DLing an app called OTG Troubleshooter to see if that would help me. When connecting the drive it tells me that OTG is detected, but that "Mass storage USB device is not detected in linux/android". Does anyone know what the problem is?
Thanks in advance

Nexus Media Importer
I had a similar problem with the device not recognizing the OTG cable, it went away after I installed the Nexus Media Importer.

I tried with Nexus Media Importer as well, no success there either, it doesnt detect the drive. Thanks for the tip anyway

mine usually recognizes the cable, it is the thumb drive attached to it that it usually dosent see

im no expert but i was having issues with a physical keyboard through otg
on stock rom it times out
im on cm12 may 30 2015 with elementalx kernel
after flashing i plugged in the otg with the wireless keyboard reciever
nothing. worse than stock.
i downloaded all the usb otg helpers etc what not
in conclusion
i somehow managed to get
s3c usb host drivers for android
installed them from some site that i cant remember anymore -- really dumb --. seemed sketchy but had nothing to lose

I have the same problem and have just tested that connecting a mouse or keyboard to the otg works without problems, what doesnt work is a flash drive. ( I have tried different flash drives to no success)
Does anyone know what the problem might be?

I uninstalled and then reinstalled it again and now it is working again. I think it might have been slow to update

Maybe you guys are using a Kernel with OTG+Charge option? if yes the problem maybe that you have to connect the AC charger and USB device together. If you don't need the OTG+charge you should deactivate that function.
