USB card reader

[Gregory Gulik]

Do you have a flash card in there?  If not, the READ CAPACITY will fail 
and there's really not much you can do with it.

Make sure there is a memory card of come sort in there.

BTW, I don't know if anyone has mentioned it but when dealing with USB 
devices "devlabel" is your friend.  Once you figure out the device name 
the first time use "devlabel" to label it so you can mount it by a 
special symlink instead of the real device which is likely to change.

Read the man page, it's pretty simple.
