I have a Canon FB630U USB scanner I and I am having trouble getting consistant operation with it on a UHCI system vs an OHCI system both running Ubuntu 7.10 2.6 kernel..
The system that uses the Via chipset exhibits a strange problem. When you plug in the scanner, or boot witht he scanner already plugged in, and you try your first scan, either with scanimage or xsane it just hangs for an indeterminate amount of time. Sometimes it will start the scan after a minute or two and sometmes it will never start the scan. Sometimes you can here the scanner "recalibrate", but thne nothing more happens. Here is what scanimage -L reveals $ scanimage -L device `canon630u:/dev/usb/scanner0' is a CANON Canoscan FB630U flatbed scanner Now I try the same scanner on a Compag system, OHCI, and it works first time every time. No hesitation. Works perfectly. I also have a Slackware 12 installation on the Via UCHI system and it exibits the exact same problem as the Ubuntu installation. So, why is it working on one system and not the other? 999alfred ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
