[sane-devel] USB HP scanner problems

[Peter Kirchgessner]

Hi Bob,

my experience with a HP ScanJet 6350 is that it can not be used with
SCSI and USB at the same time. If the scanner finds a SCSI connection,
it is not available on the USB. Try to unconnect the scanner from SCSI
and try it with your USB box alone.
