I've recently bought the Trust 420A 4 Port Compact USB2 Hub. On the http://www.qbik.ch/usb/devices/ there is a suggestion that it is Linux compatible.

In Slackware 10.1 when the hub is connected to my Canon N670U scanner, start Kooka, the scanner is recognised but when I try to scan nothing happens. Close Kooka down and start again the scanner is no longer recognised. Unplug the USB cable the machine crashes. In dmesg I get the following

The Scanner works perfectly if plugged directly into a usb port on the mother board. Also the scanned works perfectly plugged into the external hub using knoppix.

Originally Slackware was loading the uhci module whereas Knoppix was loading the usb-uhci module. I've changed slack to use usb-uhci module, still crashes.

Any suggestions?

Thanks in anticipation.
