[PATCH] USB scanner.c: Adjust syslog output

This patch prints the vendor + product ids of the scanner after it has
been successfully detected.

Also the annoying error message about "Scanner device is already open"
was downgraded to a dbg. Scanning for devices while one scanner device
was open produced several 100 error messages in syslog.
