[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.

* - Removed PV8630 ioctls. Use the standard ioctls instead.
* - Made endpoint detection more generic. Basically, only one bulk-in
* endpoint is required, everything else is optional.
+ * - New maintainer: Henning Meier-Geinitz.
+ * - Print ids and device number when a device was detected.
+ * - Don't print errors when the device is busy.
