What I forgot to tell, printing works fine (same device: it's a 
printer/scanner/copier combi) and as said, when running saned in debug 
mode (saned -d) it also works fine! Just that it quits after the first 
connection of course. But the scanner is detected correctly both 
locally and over the network. So I'm pretty sure the port permissions 
are OK. I suspect the combination with inetd that is the problem.

Snippet of /proc/bus/usb/devices:

# scanimage -L
device `epson:libusb:001:002' is a Epson CX3600 flatbed scanner

# ls -l /proc/bus/usb/001/002:
-rw-rw-rw- 1 root root 73 2007-05-17 13:56 002

Permissions seem OK to me...
