YES!  That did it.  Thank you very much!

# sane-find-scanner

found USB scanner (vendor=0x03f0, product=0x0305) at libusb:/dev/usb:/dev/ugen0.2

# scanimage -L
device `niash:libusb:/dev/usb:/dev/ugen0.2' is a Hewlett-Packard ScanJet 4300C flatbed scanner

# scanimage -v > foo.pnm
scanimage: scanning image of size 1240x1712 pixels at 24 bits/pixel
scanimage: acquiring RGB frame
scanimage: min/max graylevel value = 51/255
scanimage: read 6368640 bytes in total

# pnmfile foo.pnm
foo.pnm:        PPM raw, 1240 by 1712  maxval 255

However, it takes a _long_ time until the scanning starts
(about one minute).  Then the actual scnaning takes only
a few seconds.  The delay is independent from resolution,
scanning mode and size.  I'll need to investigate what's
causing this.

Best regards
