My computer doesn't recognize my tablet.

do not buy a new one... the problem is not a cheap usb cable. open the back part of the tablet and carefully remove the small plastic rings securing the plastic grid that should be inside, on the topmost part of the grid there should be some lines, clean them with a tissue or toilet paper and do the same for the ones on the circuit board (be sure to do it in the same direction as the lines) and put it all back together making sure the siny part of the plastic grid is facing you and that should fix it.

hope this helps

It's a problem with the cord. Mine was like that and I found out that, when pulled taut/stretched, it was recognized. This means that the tablet has a REALLY cheap USB cord, and probably has a break in it. If I wouldn't have reconnected my cord incorrectly after replacing it, and burnt out the chip, mine would recognize fine now. Time to buy a new one, I suppose....
