Since the device is not configured, it must be failing the probe. The probe just reads a byte from the CMOS. The byte encodes the 2 floppy drive types. Bits 0-3 are for drive 1, bits 4-7 for drive 0 (order?). Only a few of the 16 possiblilities for each drive are supported: 0: no drive (device not configured) 1: 360K (screwed up?) 2: 1.2M 4: 1.44M other: ?
