I've just downloaded knoppix build 2003-01-01

It booted fine and detected all my USB 2.0 peripherals (harddrive, CD-R/RW, hub, pcmcia host controller) but they've come up only at USB 1.1 speeds.

Does anyone know how I can make it run at the full USB 2.0 speed?

The harddrive is so slow at 12 Mbps!
Thanks
