No USB access but need to root
I have a tf700 with a strange problem. When I plug it into the computer, it reports there is an error in the USB descriptor and doesn't install the drivers. I know the drivers are installed OK because I have a 2nd tf700 that installs fine. I also tried linux with no luck - lsusb reports nothing when I plug it in, but it does find the other tablet fine.
The error occurs in MTP, PTP, debugging option on or off, and fastboot. It charges normally through the port.
I disassembled the nonworking unit and swapped the port/cable assembly but the problem stayed with the tablet. I also reflashed stock from SD using the stock recovery with no effect.
My goal is to get root access and install TWRP. Does anyone have any suggestions? Is there a way to connect to adb wirelessly without root access or is there an older version of stock I can flash and self-root without a PC?
