Looks like the
serial_number()
function will not populate the serial number on the devices when using thenusb
backend, so this PR moves theread_serial_from_device
function to the genericBackend
implementation, and reuses it in thenusb
backend.I also noticed that the top-level
read_serial_number
and theread_serial_from_device
functions were exactly the same except for the interface, so we're now reusing the backend to serve the request instead of duplicating the code.
