After having severe problems with my install (data corruption on internal storage) I tried to recover my tablet. I had a custom rom running before, my laptop was doing ADB shell and fastboot just fine.
When trying to recover, I found out that my USB connection was not working at all. So not even a unknown device, just silence, like tablet was powered off. Not in recovery (TWRP) nor in fastboot. Tested on linux, windows and iOS. Just no signal of a connecting device at all.
After struggeling a lot, (recovering my tablet with only an unreliable recovery) I've got my tf700t in running order. But still no USB connection with pc.
I tested my cable with a tf201 from a friend, my (new) cable is ok.
USB connection is not working on tablet itself, nor in docked state. USB debugging is enabled on TF700.
This summer during holiday (before the corruption of course), my old charging cable was bad, I had to move and turn it before it started charging. It was partly broken. At home I threw it away, so I cannot investigate that cable anymore.
My assumption is that with that defective cable, my usb data lines in the connector received an too high voltage and thus my usb controller is defective now.
USB devices like storage devices connected to my Tf700 work normally.
So; how can I find out that this is actually a hardware error? I'm not afraid to open the tablet, but I think I will not see a problem. I don't know if it can be fixed.
If it is software, which I can also imagine, how could it be fixed?
