I've got a netduino 3 that I've been using successfully for a while now. Tried to connect it earlier this week for the first time in a month or so, and couldn't get it to connect with USB. I'd get one of 3 errors: (sorry for the vague wording, can't quite remember and it's worse now)
- Unknown device with "Device descriptor request failed"
- Unknown device with"Configuration descriptor request failed"
- "Netduino" with a yellow ! and "device could not be configured" when looking at the status
Got it to connect in bootloader mode, and tried re-applying the latest firmware (4.3.2.2). NetduinoUpdate tried to do it's thing, but said "Error: Verify failed". And now plugging it into USB normally doesn't do anything, although I can still get into bootloader mode.
Did I brick it somehow? Is there anything else I can try before giving up and ordering a new one? If not, is there any chance this is under warranty somehow such that I could get an RMA from adafruit for it?
