I have a computer with a VIA VT82C686 chipset which uses the UHCI usb driver of the Linux kernel. I'm running 2.6.9-rc3 now, but also tried 2.6.4. I have a couple of usb-storage devices which don't work in this machine. Plugging one in and modprobe of usb-storage (hotplug disabled for debugging) produces log lines finishing with those below. That is for an Oracom ORC-200M, which should appear as a 128Mb sda1 partition in the end. It appears in /proc/scsi/usb-storage/1 but has lots of "Unknown". It doesn't appear under "Attached devices:" in /proc/scsi/scsi
Coincidentally, I also have an ORC-200M and VIA chipset running UHCI drivers. Strangely enough I also had similar problems. When I tried to mount the device, the screen would go blue and say PC<->Standby but then shortly afterwards it would turn off again with the kernel module hung and being unable to attempt another mount or umount it. It worked on another machine too. The cure : a good squirt of "canned air" into the USB port on the machine. The problem was just dust, which I can only assume was allowing some kind of connection but was really flaky.
Now everything is hunky-dory - running Mandrake 10 BTW if that makes any difference because I think they use supermount rather than hotplug IIRC.
