I Googled for the T30 and didn't find anything saying that it had a USB2 
chipset in it.  I didn't find anything saying that it *didn't* have a 
USB2 chipset, either.  You can figure out whether you have a USB2 
chipset by doing "lspci -vv | grep HCI".  If "EHCI" shows up, you have 
a USB2 chipset.  If not, you don't, and you will be limited to USB1 
speeds.

If you have a USB2 chipset, you need to have the ehci_hcd module loaded.  
modprobe that if it's not in lsmod's output.

If the T30 doesn't have a USB2 chipset, a PCMCIA USB2 card will be the 
best bet.  HTH,
