[GLLUG] USB Ports Via PCMCIA

After examining the dmesg log, it appears that the USB ports only worked 
for the USB 1.x device (using uhci_hcd) but none of the USB 2.0 devices 
I tried (which use ehci_hcd).  I also found a note on the ThinkWiki 
website about USB 2.0 devices not working.  (I neglected to mention that 
the laptop is a ThinkPad.)  They had several suggested solutions. 
Rather than replace the motherboard, I elected to blacklist the ehci_hcd 
driver and see how that works.
