Irregular errors during flashing on any autopilot can also be due to bad usb cables or nearby high power transmitters/modems. The latter can radiate so much in the usb cables that it becomes unreliable. We have also very often seen usb devices fail (e.g. ftdi cables) when a 35MHz transmitter is close (<2m) to a laptop with extended antenna.

Yes i understand what you mean but mine has 5v alright.
I can program the board by using the serial port (ISP) most of the time but the usb port is not detected anymore.
When it got damaged it was during programming, it just stopped in the middle of the operation
with the indication "broken pipe"
Also during ISP programming i get fatal errors some times (1 time every 2 attempts)
which tells me that the flash memory is damaged.
