Can you provide the output of the /proc/bus/usb/devices file with everything
plugged in?  (as an attachment please).

And also all of the kernel log messages?

Also, can you try the 2.6.18-rc5 kernel out?  It has a much improved code for
handling the high/low speed issues in the ehci host controller.

Marc,
Can you try the newest kernel (2.6.22-rc4)? It has multiple fixes for USB, good chance that your problem has been addressed.
Thanks,
--Natalie

Closing this bug for no recent activity.
please reopen if still exists in the latest kernel.
