I have tried ALL the remedies suggested by the good folks here and all
have failed.  USB 2 support is compiled into the kernel, and all USB 1
devices work without issue.  Every USB device I've tried (including a
modem) worked OK as USB 2.  It just fails to enumerate ANY storage
device.

Dell say (when pressed) that the on-board ports are USB 1.1, and the
external ports (on the docking station) are USB 2.

I got a genuine Dell docking station today for £9.50 on Ebay (Dell price
£146!), and when it's connected, the extra USB ports are fine with USB 2
storage devices!!!

I suspect that there's a jumper on the main board somewhere that
"upgrades" the USB.....
