[sane-devel] New to list - need help to understand sane

[William Heidrich]

Still having trouble. Thanks if the following means anything to you.


0) the scanner works fine under windows 98 & XP
1) I have compiled the scanner driver as a module. (using RH 8.0)
2) without modprobe it is detected as libusb:001:004
3) after modprobe it is identified as /dev/usb/scanner0

Sane-find-scanner detects these and scanimage -L detects and names the
scanner correctly

When I try scanimage >image.pnm the console hangs. The trace shows write
errors to the scanner

I tried with debug option and I have attached the log I received: (I get
a similar log when I have libusb:001:004 listed in the canon630u.conf
file

Ok, found by libusb.

Your first line in canon630u.conf is

usb 0x04a9 0x2204

That's ok. It will find your scanner.

Ok, your scanner is found. Now does scanning work?

scanimage >image.pnm



Bye,
