Bug Description
Since upgrading to Feisty I'm unable to scan properly using SANE. My scanner is an Acer (now BenQ) 640BU: it uses the snapscan backend and requires a firmware upload.
Steps to reproduce:
1. Connect the scanner
2. Open kooka or xsane
3. Do a preview scan
Actual result:
After scanning, the lamp doesn't return to its former position (it's also turned off) and the scanner is "hung" - doesn't accept new commands, and doesn't show up on scanimage -L either. Only by physically turning it off and back on it is seen by the kernel again, but however the problem remains.
Expected result:
The preview scans completes normally.
I'll attach lsusb, my snapscan.conf and a dmesg if possible.

Same behavior here with a LIDE25, doesn't work on feisty, but it doesn't work with my other PC which is based on edgy with a home made 2.6.19.1 kernel.
