Well for me, the drive itself _never_ attaches properly.

I am using this motherboard[1]. The TI chipset on the mb is FW-800. All
fw ports are equal, ie. there are no fw400-only ports.
Yes, the usb port on the dive works (as reported initially).

I agree, it seems bad. :-)

I'll try this another day (the box is busy now, recording).

The output you got already _is_ with debugging enabled (ie those two
sysctls you asked for).

Well that's wrong. Therer is only one thing connected to firewire ports
when the test was performed: the Maxtor drive.
Does the controler count as one port?
