Looking at the firmware source, I think this is normal, but I'd still
like someone to confirm it.

This turned out to be because I didn't have libusb-dev installed when
I built librfid, so rfid_readers[] was empty.  Now I have it, running
'librfid-tool -s' gets further, but does not detect an openpcd-branded
mifare-classic card on top of the reader, saying only:

	opening reader handle OpenPCD, CM5x21
	scanning for RFID token...

With today's librfid (revision 2089) and DEBUG_LIBRFID defined,
I see several different errors reported on successive runs, e.g.

The above were done as a normal user with a card near the reader,
but I get similar errors as root and/or without a card in the field.
