Ok, More update.
I have finally managed to compile 2.3.99-pre1 kernel. I had to remove some stuff to get it to compile, then had to remove damn near everything else to get it to boot. I had about five stops: just after unpacking, ppp, fd, partition check, daemon startup. Blah.
Well, the good news is I can mount /proc/bus/usb and get the two files, devices and drivers (after insmod usbcore, insmod usb-uhci). I can plug in the Epson, and I can see lines added to the devices files, with the correct manufacturer EPSON and product PERFECTION 636. I can insmod scanner, and the devices files goes from "no driver"--->"usbscanner", so I know the scanner module is claiming the epson.
I am unable to do 'insmod scanner vendor=04b0 product=0101' because insmod complains about a 'b'. When I change 'b' to 'B', it complains about 'B'. What, insmod no read hex?
I also know that the scanimage is doing something to the scanner driver, because when I try to rmmod scanner, it tells me device or resource is busy, but only when scanimage is running (and scanimage takes forever! several minutes)
Anyways, the bad news is, the scanner still won't work. Here's the log of the commands I tried:
vaio:~# scanimage -d epson
vaio:~# scanimage -v -d epson
[epson] ident failed
scanimage: open of device epson failed: Invalid argument
vaio:~# scanimage -v -d /dev/usbscanner0
scanimage: open of device /dev/usbscanner0 failed: Invaild argument
//note - this command executed immediate
vaio:~# scanimage -v -d epson:/dev/usbscanner0
[epson] ident failed
Segmentation fault
vaio:~# scanimage -v -d epson
[epson] ident failed
scanimage: open of device epson failed: Invalid argument
vaio:~# scanimage -v -d epson:/dev/usbscanner0
[epson] ident failed
Segmentation fault
vaio:~#
If anyone has been able to get the epson perfection, or similar model up and running, please let me know which kernel and usb-backport (or development kernel) you are using. Any info is much appreciated.
Thanks in advance,
Torsten
