libusb: add debug message on adapter not found due to wrong serial
When few adapters of the same type are in use, the serial string is
the way to select the right one.
Currently a serial string that does not match any of the connected
adapters will just fail the open, without specific information to
track the issue.
Add a specific message to highlight that the open failure is caused
by a serial mismatch.
