I have an external Fujitsu handy drive where I mount /home/knoppix, but it is mounted only as usb1. Redhat 9.0 mounts it as a usb2 drive, and is really faster on disk transference and directory browsing.
I think there is a lot of people with same problem. usb1 is too slow for disk storage system.
It is planned to add usb2 support on knoppix before kernel 2.6?
