Comment 1 for bug 34551

Sorry. Need more sleep. This is on dapper, not breezy. Worked fine on breezy.

Here is the problem in a nutshell:

jb@nonesuch:~$ sudo scanimage -L device `epson:libusb:004:008' is a Epson GT-9700 flatbed scanner
device `epkowa:libusb:004:008' is a Epson Perfection 2450 flatbed scanner
jb@nonesuch:~$ sudo scanimage -d epkowa:libusb:004:008 >/home/jb/test.pnm scanimage: sane_start: Error during device I/O
jb@nonesuch:~$ sudo scanimage -d epson:libusb:004:008 >/home/jb/test.pnm
scanimage: sane_start: Error during device I/O

Perms are set fine on the device but can't even do it as root as shown above. Strace shows many, many attempts to access device resulting in "-1 EAGAIN (Resource temporarily unavailable)". Does not matter if scanner is on USB hub or directly attached to PC.
