The enclosure is smeared across the kitchen table at the moment (see
below), so I can't give it's exact reaction to suggestion, but I have
some representative output.

In the course of mucking around, I've tried various combinations of
'fwcontrol -r' and 'camcontrol rescan all'.  I'm not sure which caused
which part of the dmesg output below, but it might be interesting:

  sbp0:0:0 request timeout(cmd orb:0x163ca634) ... agent reset
  sbp0:0:0 request timeout(cmd orb:0x163ca76c) ... target reset
  fwohci0: BUS reset
  fwohci0: node_id=0xc800ffc0, gen=6, CYCLEMASTER mode
  firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me)
  firewire0: bus manager 0 (me)
  sbp0:0:0 request timeout(cmd orb:0x163ca9dc) ... reset start
  fwohci0: txd err= 3 miss Ack err
  sbp0:0:0 sbp_reset_start failed: resp=22
  firewire0: split transaction timeout dst=0xffc0 tl=0x30 state=4
  sbp0:0:0 sbp_reset_start failed: resp=60

I figured out how to ask fwcontrol to tell me more about the device
inside the enclosure, and discovered that it's a Prolific PL-3507.  A
little googling about suggests that it's a well known PITA device, e.g.

  http://forum.rpc1.org/viewtopic.php?t=25140&postdays=0&postorder=asc&&start=0&sid=0a359d410cfd87df72f2543365922421

So, I'm left to decide whether to muck with the firmware or just chuck
it.....

Are there "quirks" for firewire devices like there used to be (are?)
for usb devices?
