   My first rule of thumb, if it doesn't work with a hub, then try it 
directly.

   It looks like the USB port is not reading the drive correctly.  Since 
this is a microSDHC, have you tried using another adapter to put it in?  
I've run into a similar problem when I used a different manufacturers 
adapter on one of my Sandisk cards.  (I'm using a laptop, so the card 
reader is already built into my computer.)

   Also, have you tried running lsusb -vv?
