| |
If a USB serial device is unplugged while there is an active program using the device it will spam the logs with -EPROTO (71) messages as it attempts to retry.
Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output these messages for debugging. The generic driver treats these as errors.
Change the default output for the generic serial driver from error to debug.

Notes: Minor change just fixes the wording in the log message.
