I had a similar driver problem with my add-on card reader recently. The
driver update completely disabled the device, but "Roll Back driver"
fixed the problem immediately. I've heard many people complain about
this process, but this is the first time I've seen the evidence.
System restore might be of some help with this problem, but I think I'd
look into the BIOS first, to make sure the port is detected and enabled.
