Right, but for the driver to understand a HAL-device name (e.g. name 
containing ":libhal:" it needs to be able to map the given name to a specific 
device (well, at least when there is more than one reader in the system).

There is no way for a HAL-agnostic driver to deduce the device address to be 
used with Libusb from a HAL device name...

That's why I asked before: Does PC/SC fall back to libusb names if the driver 
doesn't understand HAL (or deviceKit ord whatever new they come up with)?

It would be very nice if pcscd retried with a ":libusb:" name if the driver 
doesn't understand ":libhal:"...
