It doesn't sound a very good approach the need of recompiling the driver to
allow it to work with a broken card. The better would be to have some modprobe
option to force it to accept a certain USB ID as a valid ID for the card.

The above is really ugly. IMO, we should replace this by
ARRAY_SIZE(dibusb_mc_properties.devices). Of course, for this to work,
num_device_descs should be bellow devices.

Patrick,
