It looks like you have a very flakey bus. The BSY line is probably
glitching. In the trace you provided, we successfully selected the
device at ID 3 and are waiting for the target to take us to the first
phase. The REQ for that phase never occurs and in fact the BSY line
is not always driven. Very, very weird. The target controls both
the REQ and BSY lines, so this is either a problem with the target,
your cabling, or your termination.
