The hotplug system wasn't able to detect my scanner correctly before the following line was added:
scanner 0x0003 0x05d8 0x4002 (all other fields are zero)
I hope this line could be added to the core-system configuration files.
The scanner is an 'Mustek ScanExpress 1200 UB Plus flatbed scanner'. It doesn't have a power cord, but uses the USB interface instead.
Steps to Reproduce:
My /etc/sane.d/gt68xx.conf also required a few modifications to work with the
scanner, but perhaps this should be submitted in a different bug-report (?)
usb 0x05d8 0x4002
afe 0x20 0x02 0x22 0x03 0x1f 0x04
The SBfw.usb file was found on my Windows XP partition, even though Windows XP
isn't able to interact with the scanner at all. ;-) (Windows 98 worked fine)
There is no more USB scanner driver, so you don't need it loaded :)
Just use the lastes sane code, which uses usbfs to talk to the device.
