    Default Samsung Galaxy Tab 2 7.0: Usb device not recognized.

    Hi!

    I've got a little problem with my galaxy tab 2. It won't connect to my pc. It says usb device not recognized. I'm running android 4.1.2. The computer is running windows 8 64-bit and samsung kies is installed.

    I've tried on my netbook to which is running windows xp 32-bit, but no luck.

    Could it be the usb-cable?

    That or a different port. But something else to try is downloading and installing drivers and restarting the PC. But since 2 different PC are showing the same problem, it most likely is the cable.

    I've tested all the usb-ports on both computers with the same results. I've tested uninstalling and installing both kies and the android usb drivers on both computers, but with no luck. When I connect the cable to the pc it's charging, but the computer won't recognize it. When I plug it in into the power outlet in the wall it charges just fine. So I think it has to be the cable.

    Or am I wrong

    Some cables are charging cables and only have the ability to charge your Tab. Try restarting your Tab and if this doesn't work, change the cable. When you plug in the cable to your computer it may take 15 seconds to be recognized. I think this has to do with spyware software! So wait for this to happen!
    The cables are available on Ebay for a couple bucks each so I always have a spare for charging and data!

    Hope this helps!

    Cable may have gone bad. I would replace it.

    It's a data transfer and charging cable. In Sweden, those cables goes around 23 dollars or 150 SEK. Found those cables on Amazon for around 4 dollars, but if I buy of Ebay the delivery time is 3 weeks.

    No idea. I honestly wouldn't be inclined to try it.

    Hey... Can anyone tell me how do I know that it is a charging cable or a data transfer cable?? Does it say that it's charging/data cable?

    Unfortunately, there is usually no indication our marking on the cable telling you of it is charging-only...

    In my case I have a Dell Laptop with Windows 8.1
    First I had to install the additional Media Pack KB
    Then, this is the problem I face.

    1. if the Tab battery is drained, then the PC keep popping the message
    2. If the battery is half charged and the tab in os, Windows recofnize it


    So, I charged it with the wall adapter and the n plug it into my PC when is turned on.
    I don't get the annoying message anymore

    All of the cables i have seen for the Tab-2 are 4 conductor data cables! The Tab-2 uses the 3rd and 4th wire in the cable to tell it the charger is connected to has the capacity to fast charge the tab! I always keep a couple spares because the Tab-2 is useless without the proper charging cable!
    You can find these cables on E-bay for under $5

    I've started to have exactly the same problem with my samsung galaxy tab 2 7. But in my case, I don't think that changing the cable will work, because I've been able to transfer files just fine with this very cable uptil now. Can you give me any other suggestions? I'm really worried that it's a hardware problem with my Tab.

    I have the same problem. I really don't think it's a cable problem. I plugged my tablet in this morning and as I was about to transfer my files I inadvertently pulled out the cable (silly, I know). Now it's completely impossible to make the laptop recognise the tablet. I tried switching everything off and on, turning one thing on before the other etc etc. I thought I'd made progress when I received a pop up could saying my tab could "perform faster" but it was quickly replaced by the usual one telling me the tablet wasn't recognised. I now have a very full tablet that won't even let me open my pictures or use some of the aps. Also, I don't have the USB icon on the tablet anymore even though it is charging fine when plugged into the laptop but turned off (battery icon is crossed off to show it won't charge if turned on).
    Thanks for your help if anyone has a clue how to solve this.

    You know I'm having a similar problem here. Here's what my problem is. I had flashed my tablet with the CWM 6.0.2.3 version and now I cannot get my tablet out of the recovery mode. Trying everything that I can think of with no success. Just trying to keep it charged until I get home so I can try to get my tablet back into download mode and see if I can somehow flash the stock ROM back onto this thing. If anyone has any suggestions as to things that I could do in the meantime to remedy this situation, I sure would appreciate any help I could get with this.
