I had been using a an older un-powered 4-port USB hub/card reader combo
(it was powered but its psu stopped working) . I can use that, I
suppose. This unit occasionally stopped working for no apparent reason,
though - probably a power problem.
I really only want to use one USB port on the PC for neatness - it's a
laptop and the three other USB ports are on the right hand side of the
case, facing where the mouse usually lives.
