I figured this one out finally! I noticed a USB driver called USBHS DFU
Adapter. I wasn't sure what it was so I did a web search for it. I located
an article that said that a update to this driver had hosed his flash card
reader. I rolled it back to the native Windows driver and guess what?
Everything works now.

The bad driver is: "USBHS DFU Adapter SCM Microsystems Inc. usb software
update released on February 18 2005". Not sure where this update came from,
but it's gone now.
