Supplementary information: My system also has a SCSI card with a couple of CD-ROMs on it, so that's scbus0 and the firewire is scbus1. I just tried removing the SCSI card and the firewire is zooming along (8MB per second!) This may or may not be a red herring - perhaps it's just the fact that I did a reboot - but is it possible that something is wrongly assuming the device to be on scbus0 when it's on scbus1 ?
