  FYI, from what I've read, some of those devices violate the USB
spec, in terms of power demands.  In particular, the idea of hanging
two USB A connectors off one cable does nothing -- the USB spec says
devices have to negotiate their power demands with the host
controller.  Or so I'm told.  These things frequently happen to work
anyway, but one should be aware of this.  I'd recommend buying from a
vendor with an easy returns policy, just in case.
