<b>I had the same problem except my USB is dead too. 5 day old tablet. Mine would not play any games properly, so it said to try updating drivers. I went in under device driver and started to download drivers. The first 2 were a success. Then the next was to update the firmware. I was surprised that it would be that easy, so I did, but before you could stop it it downloaded firmware for a Teclasts tablet and installed that, now a brick! </b>
