entirely fair :)

I forgot to mention that both drivers fake the get slot status command
when they can't reach the reader to say the slot is empty, so you can 
hot-attach the reader and then pcscd just sees a card insertion.

The ACR3901U driver additionally remembers if the card was powered
and restores this state on reconnect, so things like ssh-agent + pkcs11
work seemlessly.

I may have a spare if you can't find it (i bought more than one), as I think
I'm going to use the ACR3901U-S1 as they're much ligher and smaller and
fallback to usb when the battery is flat.  (They're also cheaper at about $35 )

I didn't bother reverse engineering the windows tool that sets the PIN over 
USB as that's a once only operation.
