Bug Description
scanimage is blocking when trying to read my Epson Perfection 2450 USB 2.0 scanner in breezy.
$uname -r

$sudo dpkg -S libusb

Detailed log available upon request. This is a showstopper for me. Worked fine in Hoary with hotplug. udev seems to be a trouble spot for usb.

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