[Q] Usb connection error, usb not recognized - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hy everyone!
I have problem with my samsung galaxy tab P7500..it wont recognize my usb. in notification bar shows that is connected but it is not. there is no folder od something with my usb staff. it worked fine, and then just stopped. i dont know why
before, when i connected usb, tab opened a folder of usb, but now nothing..
did i miss something? where did i get wrong??
please heelp!!
P.S. sorry for my english

Switch to a different USB port. It seems like a stupid answer, but it is a common problem. Switching from the form factor USB ports (front panel) to the board mounted ports (rear panel) or visa-verse often works.

i know this may be an old post but here goes, i have the same problem, my PC tells me that the drivers for my tab are installed but i can not see it in my PC.
i connected it to different USB ports but still i can not see it.
i tried turning the debugging on/off still to no successes.

Try unistalling kies and the Samsung drivers, restart the pc and just install the driver. See if that works.

Okay, I just googled your problem... Try removing the device from device management (sorry, it was a Dutch site, translation might be different) in Windows. Then reconnect it.

Then I only have 2 more options available before I run out of ideas.
1) did you enable mtp under the storage options on your tab?
2) your USB cable might be defective. Try a different cable.

Ah, great! I'm glad I could help

Hi
Hope somebody could help me.
my tab is p7500. official ics and rooted. i try to connect usb otg and it working by showing "USB connector connect" .
I can connect it with 1gb flash drive. But when i connect with 2 gb flash drive or higher, the tab will show "High-power usb device connected. cannot access to this device".
why it show like that? is the tab only can access flash drive with 1gb memory and below? or there is some setting that need to be done if want to connect with higher than 1gb flash drive?
Please see the picture attach...

i don't think that the p7500 supports more than 1gb of memory. i don't think that i have a flash drive in my p7500.

I can't believe that the p7500 wouldn't support flash memory over 1gb. I've heard of people using a USB hub that has it's own power supply for OTG.

I like to just share a PC drive or folder on my network, then us ES File Explorer to find the video on your network and stream it over wifi to MX player on the droid. It's a little technical to set up, but a good thing to know.

What can i do to fix this problem?
anyone know this problem?
Looks like a drivers problem to me, if you didnt already, try to reinstall latest version of Kies (but dont forget to kill the kies process before using Odin if you plan to use it)

I tryed to reinstall Kies and drivers but with no succes.
I have this problem too and i resolve it by turn the plane mode on, don't know why but now all is ok ..
Try this.
1. Go to settings --> wireless and network --> usb --> usb mass storage
2. connect the usb cable
3. turn the usb mass storage (the android icon changes to orange now)
Go to my computer and you will now see phone and sd card storage as seperate....you should be able to copy fine now.

Hello!
I know this topic is old but I had the same problem with my Galaxy Note this morning and the solution was to disable USB Debugging.
Just to at least mark this topic as solved.

I had this problem with my Galaxy Note 4. I was using the original USB cable which was supplied with the phone. The error was showing up at random stages of the file transfer process - sometimes near completion, sometimes after a second or so; which indicates to me that it may be a hardware problem. So, I then tried using a different USB cable (cheapie from eBay), and it works fine! No brainer fix :silly::silly:
Same issue here - bad cable again in my case. Got a decent quality one and it works fine.
This worked on my Note 4 - Simple Settings -> Developer opions -> Check USB Debugging

Samsung Galaxy S3 not recognized (with drivers)

I have installed Samsung USB Drivers manually and also tried Kies to install the newest drivers, but my Samsung Galaxy S3 still isn't recognized by my computer. What can I do?
EDIT: It only works sometimes, so when I plug it out and in like 10 times, maybe I'm lucky and it will connect once.

I have the same problem. My VSGS3 works with my W8 laptop but not my W7 desktop (at all). The only thing I can assume that it would be is MTP issues with Truecrypt (my desktop is encrypted). I cannot get it to work at all.
take a look at this thread...

You can use MTP mode to copy the files to the computer.
The device will appear with a phone-logo in 'My Computer'
Just plug Samsung USB cable into USB port on a PC with the Samsung USB drivers installed and cut and paste as many GB as you want .SD Phone or EXT SD card via Windows Explorer as normal .

This problem is quite depressing Has a restore fixed it for anyone?
I use mac OSX and after searching for a month or so, I couldnt find a solution to connect via USB. So now I use 'Air Droid' app from Play Store. Its pretty good and simple!! Plus, you can do alot more stuff like send or read SMS from PC.. Dont need to connect via USB anymore
I found that installing that rootkit installed the drivers to connect via USB - didnt root it just installed it for the drivers. THANKS!
I am having the same problem.
My Galaxy S3 charges when connected to computer via USB.
But is not detected in USB Debugging or regular mode.
Which windows version are u using. Try installing pdanet.exe on ur pc

You must know what windows you use, 32 bit or 64 bit? Download Kies through Samsung website, make sure got right software.

If you are using x64 Windows 7 this will EXE file can be found here:
C:\Program Files (x86)\Samsung\Kies\USB Driver\SAMSUNG_USB_Driver_for_Mobile_Phones.exe
back this up and then you can remove KIES. This is all you need to have your phone connected without ever really needing KIES.
Or you can use the driver provided by the TOOLKIT that MSKIP has designed (thanks - love it).

nothing has worked for me. I have not tried the toolkit but I installed drivers from the TeamEpic's easy root as described by QBKing77 and those have not worked since I installed twrp
One more to this incredible situation :angel:
experienced the same on my win7 64 bit. I removed it on the faulty usb port to another one and then luckily the driver installation went fine. Weird but worked.

instead of USB try MTP mode and see
same in MTP as well
Try ticking "USB debugging mode", that will make your phone storage recognisable by the computer as actual drives instead of virtual drives. If that doesnt work try mock locations, I heard that can solve some problems if theyre on the computer end.

Me too having the same problem ...Is it solved or yet to be solved ??
Are You rooted?
Give full info about phone...
Problem could be with your Cable or USB Port.
Try changing USB Ports.
If you are Confident about USB Port working well.
Then Try changing a Cable. Always Use original One. And Dont use large cable as it would just Decrease the data Speed.
Hope it helps, Cheers
Peace
Hit Thanks & It will Disappear

I am not quite sure but if you are on a custom rom sometimes some problems like this exist. But if the stock firmware donno whether its the Software error or the cable. So just try update cable with another one.
To help you more I need some more details. So that I can help u

Unable to use "USB Mass storage" on my Galaxy S II

Hello All,
I got my new Galaxy S II yesterday and it came with ICS. I am trying to connect the phone on to the PC as Mass Storage - but as soon as I connect my phone, my PC (Which runs on XP) says "USB Device not recognized". I tried USB Debugging, enabling Mass storage under Settings->More->USB utilities etc. Nothing works. I even tried with a different cable - no luck. Can anyone help me to fix this issue? Thanks a lot.
Read this -
http://www.jayceooi.com/2012/03/14/...storage-on-android-4-0-ics-samsung-galaxy-s2/
USB mass storage was removed by default in the ICS upgrade. Now the S2 uses MTP, similar to the Galaxy Nexus. Windows 7, Ubuntu & OS X can read it, but XP doesn't have MTP functionality built in. I guess it can be enabled though, don't know how. In any case, USB mass storage is still accessible, follow the link.

USB alimentation, UMS, country version...

Hello,
I just got my i9100 (and surprisingly not a G neither P..!) and i have few questions. It's running on ICS LPW firmware. First I'd like to know how i make sure this is a phone from my country and not another.
Next i'd like to know how to know how to be in UMS mode (mass storage transfer) when i connect the device to the computer, without having to go in settings, plus, usb, mass storage...
I've had a Galaxy Note before and when pluging USB, i just scroll down notifications, select usb and then just switch to UMS... Here selecting USB in the notification bring me to choose either MTP or some photo mode...
Last thing : Is there a way to make the i9100 able to power on some 2'5 external hard drive (i have Western Digital Passport) just like the Galaxy i9300 (SIII) can do? I just tried and nothing happened... Maybe with some other kernel..?
Thanks.
