I'm using sane 1.0.15, libusb 0.1.8, linux kernel 2.6.6, gentoo linux. /etc/sane.d/dll.conf has the plustek driver listed:
# cat /etc/sane.d/dll.conf ... pie pint plustek #plustek_pp #pnm qcam ricoh ... And my Canon LiDE 30 shows up here: # cat /proc/usb/devices ...

A bit more info is appended below. Any clues? I had this scanner working under linux 2.4 and a different distro, and googling around seems to suggest it's a 2.6 kernel issue, but I couldn't find any resolution to the problem.
