Description: usb scanner not work (multifunction printer EPSON DX4250)


Additional info:
If remove module usblp scanner work, ..and printer no, I found this solution in this post (speak of patch required to sane)
http://lists.alioth.debian.org/pipermail/sane-devel/2005-September/014721.html


Steps to reproduce:
From root search scanner with command:

bash-3.2# sane-find-scanner

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04b8 [EPSON], product=0x0820 [USB2.0 MFP(Hi-Speed)]) at libusb:002:012
found USB scanner (vendor=0x046d, product=0x08da) at libusb:001:003
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
bash-3.2#

After this add command:
bash-3.2# scanimage -L
