[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
GT-P7510
Android 3.2
Rooted, TASK 14 Rom

Try to reboot, it worked for me.

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?

[Q] Usb host on the go

Is there native support for Usb Host (like Samsung GS2)?
PS: I read the FAQ,but I didn't fount any video showing a nexus plugged to a usb pen o other peripherals

this was actually pointed out many times
yes it is supported
it was even mentioned on the launch day event on stage

Here is an article that gives more info on it...
http://www.androidpolice.com/2011/1...behind-galaxy-nexus-lack-of-usb-mass-storage/

USN Mass storage no, but USB Host yes ???
I'm utterly confused. If you look at
http://www.reddit.com/r/Android/comments/mg14z/whoa_whoa_ics_doesnt_support_usb_mass_storage/
it seems that GN can't be mounted as USB drive to a computer - they replaced it with MTP. How come that USB Host works ??

Because this time your phone will be the host and not your PC. That the internal storage can't be connected as ums doesn't mean your phone can't play host for usb thumb drives. All the honeycomb tablets do that already and some of them also just use mtp, like the Galaxy Tab 10.1 I'm typing this from.

is it only your supposition? or you have already checked this?
as it says the link above:
"What we will probably do eventually is add an import/export concept to removable storage. So the Camera will always save to internal-16GB, and when you pop in an SD card (or insert a thumb drive on USB host devices) you can start a migration or import/export dialog."
Am I right that there is no ability to connect usb flash drives for now on this device? Sorry, English is not my native language so I could make a mistke while translate this.
Explain to me please. usb-host for usb flash devices present or not?
Thank you in advance.

Has anyone who has the phone ACTUALLY tried it?

It's strange that nobody who already own nexus from this forum didn't tried this function yet. only conjectures that "it must have usb-host".
meanwhile this is very important function for device that doesn't have micro SD support.=(

oh no! wonder if anyone with the phone can confirm this? honestly this shi* happened with the nexus S with the hdmi out. It was possible on the galaxy s, but not the nexus s. Now it seems the otg works on the galaxy s2 but not galaxy nexus. Sigh, love Samsung.

I think that it isn't samsung fault. GN have the same USB swith that Galaxy Note have. so the hardware is similar. I think the reason may be in new ICS (in that case I hope we will get host later) or in same that GN doesn't support usb mass storage (in that case we can forget about host).

My past 3 phones have been samsungs. I like the brand but I have this suspicion that they like to keep their better features for their own flagship phones. Not that I can blame them.
Would really appreciate it if anyone can confirm or deny if the otg works on browsing thumb drives.

It's neither.
ICS obviously supports it, as it was part of the sourcecode from hc and onwards.
And it cannot have anything to do with the way it connects to a pc, as that is nothing but a problem with the fact, that the storage for the pc and the storage for app-data is on the same partition, meaning that mounting this partition to a pc in ums would render the phone useless meanwhile.

maybe I don't understand but we are talking about connecting usb flash drive to nexus via otg adapter but not about connecting nexus to pc as a mass storage.
If I understood you properly correct me.

I have just tried this and did nothing, like it wasn't even connected. I tried it with a 8gb kingston flash drive and a 250gb samsung drive. Both nothing sorry.

I'm sure this will sound patronising: do you own a GS2? Does the adapter that you used work with a GS2?

No it doesn't but I think I know why, both of the drives are ntfs. Let me format them to fat 32 and try again.

You have to use a cable like this to test:

I'll be waiting anxiously. Lack of native USB Host mode could be the straw that broke the camel's back for me.

How do I mount a USB drive?

I've got 4.0.2 running - mice work fine. But how do I reliably mount USB drives? I tried downloading USB watcher OTG from the market, but the application is incredibly buggy and unstable.
Any other ways?
Thanks.

ICS and the Galaxy nexus no longer uses USB mount.
We now have something called MTP, and If you have the correct drivers installed your device should appear in my computer as a media device and then you just copy and paste as normal.
I have just had a ***** of a time getting my GN to show up in My Computer. In the end all I had to do was update Windows Media Player.

Lots of people seem to be getting these confused. I'm talking about using USB OTG to plug USB flash drives into the Nexus and then access the files on the drive.
MTP is working fine for me with both Windows 7 and Windows 8. No need for installation of drivers, it seems to be 'plug and play'.
Thanks for the reply!

ahh, got ya. I've had MTP on the brain since i couldnt get it working last night. I got it working just before i read your post

Mount command via something like terminal emulator? .. Not sure on the full details but it should be something similar, maybe?
Also I see you've jumped ship as well cjward ;-).

What a coincidence. Literally as soon as I posted this, Chainfire released StickMount, which allows automatic mounting of USB sticks in the Galaxy Nexus. For anyone else wondering, head over to the thread here:

are you running stock kernel or custom kernel.
i think unless you run a custom kernel, you will not be able to mount a USB drive.

I'm having a harder time finding an adapter that turns USB into micro. I ordered what I thought was the right product but when it arrived it's just to convert someother weird mini USB to standard micro. Anyone know the best place to get these? Preferably in the UK?

Mouse on Arc

I bought this usb adapter with have on one side micro USB and on other standard USB and I tried to connect PC mouse with my phone but the phone didnt reconize that i connect mouse with it.
Can you tell me what to do?

Let me get this right maybe I read wrong are you trying to connect phone to your pc to either transfer files flash roms etc or are you trying to connect a computers mouse to your phone? If its the second one as far as I know you can't connect a mouse to a phone with a usb, phones don't have the software or drivers to do this and to be honest why would you want to.You can on the other hand use your phone over wifi as a mouse to control your pc or even Xbox with the right software many apps in the market for this.

i want to connect pc mouse with my phone and it IS possible. if u dont belive check youtube or google it. Its possible to connect keyboard and controller too.

It is possible. It is called USB On-The-Go.
OP: Does mouse appear on the screen? What firmware and kernel are you using?

im using stock. i dont see and mouse cursor cuz it dont detect that mouse is connected. For USB OTG u need rooted phone and i didnt root it yet. And i noticed that you can burn phones motherboard if u using this for i dont know how long.

Incorrect, incorrect.
USB OTG does not require rooted phone. USB OTG is a fully implemented script for SE devices, as it has official support from Sony aswell (*cough* LiveDock *cough*).
Also, mouse only requires minimum amount of power, so there is very small chance of burning your SoC (system-on-chip). If you want to use external HDD, then it would be whole other story, but mouse shouldn't be a problem at all.

AW: Mouse on Arc
My HP Mouse is working without problems with my arc.

No. I have two devices, arc s and Neo. Every mouse I tested work, including apple, dell, HP etc. It DOES NOT matter if it is rooted or bootloader unlocked. Sounds like a faulty USB otg cable to me. Or use a different mouse.
If all is working well, you should end up with a mouse+keyboard combo like mine. Thumbdrives require root.

what capacity btw?
When you connect a pendrive, usually either of 2 things happen:
1.) shows that external storage is connected, details can be seen in settings>storage, external storage. file access needs to be done using a file manager app.
2.) shows, device power consumption error. meaning, ur pendrive consumes lot of power than the phone can provide. solution to this is to use a new pendrive or thru a externally powered usb hub.

Its of 8GB. The phone doesnt show any sign of connected pen drive and even the external storage option in "storage" is greyed out

hmm, I dont c wat is wrong, try another pendrive, prefarably of a different model or brand and of smaller capacity.
else it shud be a problem with the cable.

You can use "StickMount" app to mount USB storage , incase your phone is not detecting the USB device. The only issues is that the app needs a rooted device. so if your mobile is rooted then you are good to go.

StickMount isnt helping either

try connecting a usb mouse and/or keyboard..
if it works, try a different pendrive, else then maybe u can blame the OTG cable or ur phone...

I made my own OTG cable using an old regular micro cable that I no longer needed. I believe you need to "jump" pin four to pin five....but you would be best researching it. I recall it being extremely easy to do, but then again I do have years of experience ripping stuff apart and putting it back together.

Also, I don't think drive size is an issue as I've connected a 2TB full size external hard-drive (the kind with a power brick) and was able to use it just fine. It was NTFS formatted so I did have to use USB OTG Helper to get it working, but it did work with no problems.
