IIRC, it can be triggered by the second INQUIRY during the same firewire
session (i.e. device survives only one INQUIRY after login and using e.g.
scsiinfo -i afterwards triggers that behaviour).

Can't verify that, since the hardware in question had been met its end
(after a week spent debugging that mess).  It was of the "can't upgrade
the firmware" variety and frankly, it's easier to spend $20 on a working
enclosure than to waste time on that dreck.
