[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

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] Cant transfer ANYTHING to external SD!!

I have tried transferring files via My Files app, File Expert, Astro, as well as connecting to PC via USB... it always gives an error and says unable to write! I have also tried to transfer from internal to external SD, still just says "copying failed". I've also tried via Kies.
The external SD is not locked as I used it in a previous phone, and the Note 2 can see the files on it (and play the music).
What's going on?!?

Uninstall and reinstall drivers worked for me, I don't know what happened I went they the same deal yesterday.

My card worked perfectly for a while, then became write protected for no apparent reason and I started getting the same error message you are getting. I had to copy the contents to my PC then reformat SD card in the phone. After that it worked normally again and I was able to copy my data back to the phone .

For anyone with a similar problem described above, please try another USB cable. In some systems, the white USB cable that comes with this phone doesn't send data to computers properly - it supplies power but has problems with data.
Many people have reported this. I just confirmed it on my system. I connected my Note 2 to my system with 5 other usb cords and my system found the device every time. When I used Samsung's white usb cable the computer didn't see the Note 2.
Either Samsung did something with this usb cable or they're sending a lot of defective usb cables out.

I am using a different cable and it detects the card, but as the others have said, it is "write protected" randomly.
I have even transferred all data to internal, formatted my external SD (via the Note 2 option), moved everything back over, it wrote files fine for a few days, and now it is auto-write-protected again. This is kind of ridiculous and is really a hassle especially seeing as most people use external cards for media.
Bump for a fix hopefully... We should not have to reformat every few days just to be able to use our cards.

Thanks for the clarification. I haven't experienced this issue (yet) and agree this is not related to the white Samsung USB cord..
I wonder if the phone has problems with certain cards. What type, brand and size memory card are you guys who are experiencing this problem using?

I'm able to transfer files to and from SD card but not while in recovery mode. Only some files show on SD card while in recovery mode, backups fail, etc.. any ideas?

[Q] Why isn't my PC recognizing my phone and vice versa

I have a tmo samsung galaxy note 2, that i purchased in December. I have not rooted the phone, thus stock ROM and all. The phone is up to date with the latest updates from tmobile. just two days ago, i tried to pass some photos from my phone to the PC via USB Cable. i connect the phone to my pc and it only goes to charge the phone, no connection notifications on neither the phone side nor the PC (Windows 7 home premium 64-bit). so i went to samsung for support, and got the run around of re-install the USB drivers, re-install Kies software, etc. after the un-installs i reset the PC, and after the re-installs, i reset the PC but nothing changed. also i soft reset the phone (turn it off, take out battery for 30 seconds, then turn it on), and still nothing. i have tried all different USB ports on my PC, have used different USB cables (my brother also has the GN2 so i tried with his USB cable). tried again on my mom's laptop, brother's PC, and i get no response at all from the PC's nor my GN2. could something inside have become damaged, i mean i take care of it like it was a baby, but maybe...???
on a side note, i used windows media player to transfer music the last time i was able to transfer, but the playlists showed up in both ext and int storage, so i deleted the int storage playlist files. could there be a problem stemming from WMPInfo.xml in the both the int/ext storage card?
if i'm missing any info to help with the problem, just ask. i'd like to get this resolved asap, since transferring over Kies Air is a hassle and sometimes doesn't respond properly, since i use my phone as my main camera and like to back up all my pics/vids on to an ext HDD.

After you plug the usb in to the phone and pc are you putting the phone in storage card mode? The phone will ask you.

it doesn't ask anything. the phone isnt recognizing that its been connected to a PC. it only goes to charge the phone, nothing else happens... :/

Bad usb port, try a different one, also another basic USB fix (with other devices) is to actually unplug the CPU/laptop from its power source for like 5 minutes... have you factory reset your phone? Not really sure but this problem sounds familiar with another I heard a while ago, not exactly sure what the end result was

After re reading, if it's not ports, drivers, or bad flashing, and assuming you have made sure all your files are in order (mention of removing double files?), then Id say it's some sort of internal configuration with the settings of your cpu to your particular phone. Either some program is taking over how your cpu reads the device when plugged in, therefore causing your phone to behave the way it is, or usb ports need some inspecting. I wonder if its just MTP that is "under control" (maybe qualcomm usb "troubleshooting" could confirm this, of course Odin could too, perhaps)

i thought at first it was Kaspersky Internet Security, but if that had been the case, it would've blocked my phone from connecting from day one. could it have something to do with the ext storage card (going out on a limb here)? i ahve contacted tmobile directly, to see what they say, but i'm trying everything, even have disabled my KIS, restarted my PC and still nothing. i'll try the troubleshooting your talking about. hopefully that sets everything straight. the wierdest part is that now Kies Air is picking up my phone and all, it just isnt working over USB cable ...

also, i haven't factory reset my phone. saving that as a last resort option if all else fails. quick note, this problem seems to have presented itself after the latest Kies update. but wouldn't explain why its not responding after re-install.

Guys, I hope the following helps you.
When you plug the Note to the PC USB cable-computer, you will see the USB icon on notification bar as charging.
Pull down the notification bar with your finger and tap on the charging USB notification.
Change the setting to the Camera and then unplug the phone from USB and plug it back again.
That should work. Look in the computer for devises and you will see the camera icon on your PC and also your C drive
and other devices.
Click it and the card/phone storage part will show up.
If it does not, re start PC and plug un plug the cable.
Work for me every time.
I too run Windows 8 Pro and that is how I do it.
:good:

the problem is that the USB icon never appears on the notification bar, nor is it anywhere to be found when i pull down the notification bar. something is interfering with the phone recognizing connection to a PC's USB port...I'm using Windows 7 Home Premium x64
still haven't figured out what the problem might be. definitely going to T-Mobile store tomorrow...

Did you try another cable? Another PC?

If your brothers phone plugs in and is read perfectly fine on your PC then it's something with your phone... probably fixable with a reflash of stock.
It seems to me that your device is having an issue with MTP connectiviry (as your phones USB still charges when plugged in) and like I said, if you download the proper Qualcomm drivers for the GNII onto your pc, and use your phones dialer to adjust qualcomm usb settings (for example let's say) to enable QPST connectivity, then you could confirm its just MTP that is malfunctioning... if it's just MTP then as a troubleshooting guide, you could start disabling/reset settings to default/reinstalling apps on your phone or programs on your pc that are directly related to your phone being connected to your PC through USB (Kies, Windows Media, any other 3rd party apps or programs you may use, etc)
Eventually when disabling one of these apps you should get MTP working again (and at least then you have found the culprit-rogue app/program)
If it's not the PC (ie you still can't get connection to work when plugging into a different PC, and have troubleshot all your phones apps) then might be time to file a warranty claim

And to answer your question, yes... As a "basic" troubleshooting option, one should always try to use different SD cards in their phone to see if there is any difference!! Considering your brother has a GNII, I'd say not only do you have all the resources needed to find any problem any your phone ever has, but the resources are there to fix them as well

i will definitely take this advice and try it out in the morning. hopefully this helps. otherwise its off to the T-Mobile store.
on a side note, i read recently somewhere that the issue i'm having may be presented while using a USB 3.0 port. Even though i do not have a USB 3.0 port, i recently purchased an external HDD which runs on USB 3.0/2.0 (compatible). could it be possible that such a configuration might have caused the issue (again going out on a far reaching limb)...??

Maybe if your hdd tried to auto load something onto your phone upon plug in... considering your stock, I don't see how this issue is even happening... outside of some app/program settings or some type of "hung" connection, the basic steps you have already covered with drivers/ports etc, should have nixed the problem

okay, so weirdest thing ever. I took my phone into T-Mobile store, where they connected it to their PC and boom, it picked up without a hitch. So they gave me a new wire, and when i got home the problem was solved. the GN2 is now back in order, responding as it should. thank you everyone for your input.

I have having the same issue with a Galaxy Note II Verzion SCH-i605v and its pissing me off LOL. The computer picked it up at one point as gadget serial and installed the Samsung drivers but after that it the computer will not pick up the phone. The phone won't even be picked up on my roommates laptop. I am like please tell me what too do here?!?
also I can get the computer to pick it up in Odin mode which is so flipping werid lol any suggestions would be greatly as I would love to use this phone. I am currently using it with a cricket sim card. only getting 3G and HSPA+ at times. NO LTE or 4G. I'm trying to fix that problem but can't try unless the computer will pick up the phone.

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

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.

USB OTG/host function does not seem to work anymore?!?!?

I recently received my Lenovo / Motorola Moto Z Play and I am very happy but....
the USB OTG/host function does not seem to work anymore. This has worked fine from day one, but last Saturday suddenly no longer. I have no idea why it no longer works, there was no update, and I have not seen or heard weird things or done anything to it.
When I insert my USB C type SD card reader, nothing happens anymore. The LED of the card reader / stick doesn't even light up.
Preferably I solve this by myself, but I have no idea what to do, I did a factory reset but that brought no solution.
The data connection to PC and charging function both work fine.
It seems that the telephone does not power the USB port (anymore?), but I can not test it. All cables/adapters/SD cards/USB sticks do work in my other phone, so there must be something going wrong in the moto Z Play.
Can anyone advise me? Does anyone else have this problem too?
I need this function during my work occasionally.

It has been fixed, like a cat! Google supports it not!
Here is what support for USB Audio player said in response to why the app cannot see my drive:
Android basically does not support USB drives. Some file explorers have made their own USB mass storage driver and FAT32 handler. They set up a local HTTP server for other apps to access the selected file.

See my recent posts. This in Dumb

Yeah, well guess what, that may be true, but it WORKED and then since last saturday it doesn't anymore. If I use a powered cardreader, it works again, and same goes for connecting a USB mouse or keyboard.
To me that means that the power supply to the USB port is defective.
Does your Moto Z Play support a USB mouse? Please let me know, cause that would make my case.

I had funny behaviour about internal storage being seen by Jetaudio. It played from /music for a while then it quit being able to find it (as well as most of internal) a reinstall does not help.
I think only a firmware reflash might reveal a problem....
You could help me too. See if my complaints about OTG drives is true for you also. Do you have an OTG / memory stick adapter? If so post that link too.

The only product that stopped working is the power on the USB C port from the Moto Z Play itself. I have checked all cables, adapters, USB sticks, card readers and mice, they ALL work fine on other phones.
I can't check for you, since I can't connect to USB card reader anymore.... In my case it's simply the power that isn't provided anymore on the USB C port, while earlier it worked ok, therefore it must be broken. I'm going to have it fixed with the seller.
In your case I would say try ES file explorer or TotalCommander. Both did work great (until the power issue).
If you can use a mouse on your Moto Z Play, then you're OK. OTG should work fine then also with ES or TotalCommander.

Same problem happened to me.
After few days back, all seems to work fine but suddenly same OTG USB stopped working.
Kindly let me know how to solve this problem if anyone has done it.

Hello, I have the same problem, OTG used to work normally before. Now I found out the only way to make it work is to supply the 5V power from an external source using USB extension cable with a extra power plug (2 males, one female), which I plug into a powerbank/wall adaptor. Not perfect, but still better than nothing, OTG seems to work.

Hi all !!
I have the same problem! OTG not working, but CQATest tells DEVICE is in USB HOST MODE
