[ntdev]1394 driver loading

Hi,

I am new to 1394 driver and I just started working on a driver for SBP-2
device. Can any body tell what information Windows needs from a 1394 device
to load a driver for it? I.e., in addition to vendor ID, what else is
needed? ChipID in InfoBlock? unit_spec_id? unit_sw_version? or
unit_unique_ID leaf?

Thanks in advance

James
