Then maybe the reader does want to receive a "load" command.  You 
can use the sg_start program from the sg3_utils package to send this 
command.

You should start usbmon, then insert the card, then run

	sg_start -l /dev/sdb

The load command should show up in the usbmon log.  Let's see if it
convinces the reader to look for the card.

If it doesn't work then there's a good possibility your card reader is 
simply broken.
