Take a look at the messages in /var/log/messages when you plug it 
in, and when you put a card into it. You should see something like this:
Apr 17 14:23:54 mikkel kernel: usb 3-1: new full speed USB device 
using uhci_hcd and address 4
Apr 17 14:23:54 mikkel kernel: usb 3-1: configuration #1 chosen from

When you put in a card, I would expect to see something like:
Apr 17 14:23:59 mikkel kernel: sd 5:0:0:0: Attached scsi generic sg7 
type 0
Apr 17 14:25:48 mikkel kernel: sd 4:0:0:3: [sde] 990976 512-byte

The drive letter and generic device number are probably going to be 
different. (The examples are from 2 different devices.)
