I was in the middle of debugging when my Rhino’s USB connection to my PC dropped. I tried cycling power and nothing. I tried using different USB ports and different computers but nothing happens when plugging it in. The board was connected to a regulated 6V source.
I disconnected the servo it was connected to and still nothing. This was the only device connected to the board at the time.
If I hold down the “reset” button I can get the PC to indicate “USB Device Not Recognized”, but nothing more.
The application that was on the device runs normally (moves servo back and forth on power up)
I tried getting into bootloader and I can NOT.
Any ideas? Do I have a dead board? Is there a warrenty?
