scanner stop working after update

[Enrique Morfin <enriquemorfin@yahoo.com>]

Hi!

My system is sid.
The scanner is epson perfection v100 photo

It was working flawlessly (with iscan).

Since last system update (aptitude update; aptitude safe-upgrade)(friday morining), the scanner stop working.

$lsusb
Bus 004 Device 013: ID 04b8:012d Seiko Epson Corp. Perfection V10/V100 (GT-S600/F650)

$sane-find-scanner
found USB scanner (vendor=0x04b8 [EPSON], product=0x012d [EPSON Scanner]) at libusb:004:013

$xsane
no devices available (in little window)

$iscan
could not send command to scanner. check the scanners' status.

$scanimage -d epkowa > test.png
scanimage: sane_start: Invalid argument (and the scanner tries to do something)

$scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Any ideas? what happend?

I purged all the sane programs, and reinstalled the old versions, but still the same problem.

When the scanner is plugged:

$ls /dev
usbdev4.13_ep00
usbdev4.13_ep02
usbdev4.13_ep81


Could be sane? udev? hal? any other idea?

Thank you.
