[X-HW] Firewire Daisy-Chain

[warwick teale]

HI, yeah.. a suggestion.

May be an  issue of the failed drive may have been caused by having the 
isight camera on the same FW "hub"/"chain  as the drive. Several others 
and I had the same problem.

Method:

1) use isight camera by itself (only thing on FW path) when not powered 
from FW hub (powered externally that is)
2) if necessity - then use isight camera through POWERED HUB (external 
power to the hub) when connecting other FW devices.

Likely cause is that isight power consumption may cause some issues on 
buss... but that's a guess!

Anyway, I had a 250GB drive hosed (lost all data (100GB) worth due this 
problem.

hope that helps
