I just purchased a USB Canon CanoScan LiDE 30 scanner...the scanner is very nice, and works perfectly in sane. I even got it to scan...once. Now, whenever I plug the scanner in, it is detected, and then it quits...take a look:
Code:

That is what I get in /var/log/syslog when I plug it in...and then, in a few seconds:

I'm running debain unstable, kernel 2.6, with the latest sane stuff, and the latest libusb. If you look at the first line in the second block, it mentions ep0. I've also a TI silverlink usb cale to connect my calculator, and sometimes, if I leave it in during boot time, I egt ep0 timeout errors. I ussually just unplug the cabe, and it works fine. Any ideas?
