In my case, xsane is working fine and allows me to use my ScanJet 3300C, 
I'm really satisfied up to now.

My scanner don't work with /dev/uscanner0, so uscanner had to be 
disabled in the kernel and the generic device was used instead. 
Compiling sane without libusb might solve this problem, but I didn't try 
it. My printer also have the same problem with ulpt, I have to use ugen 
to use it.

Thus, at boot time, I get this:

ugen0: <Samsung Electronics Co., Ltd. SCX-3200 Series, class 0/0, rev 
2.00/1.00, addr 2> on uhub4
ugen1: <Hewlett-Packard HP ScanJet 3300C, class 0/0, rev 1.00/0.00, addr 
2> on uhub0

I changed the permissions of /dev/usb0 and /dev/ugen1 accordingly to 
allow users to use the scanner. But if the energy saving feature of my 
printer takes the printer down and the computer reboots (after a power 
outage for example), the printer is not detected at reboot, the scanner 
then takes ugen0. The permissions are then wrong and the print spool 
points to the scanner device. Until I find a better solution, my 
workaround is to shut both devices and reconnect them in order.

With ugen, sane-find-scanner reports this:

found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0205 [HP 
ScanJet 3300C]) at libusb:/dev/usb0:/dev/ugen1

The configuration file hp.conf had to be changed to allow users to use 
the scanner (otherwise only root could):
   option connect-device

scanimage was freezing when the last two lines weren't there. I don't 
know if the "option connect-device" is useful since sane-backends is 
supposed to use libusb, but I didn't try it without it.

Hope this helps.
