Not certain tbh; does the HD P2 have a PSU?

My understanding is that it won't get power from the 4 pin on the Shuttle. The HD P2 manual says that it will use power supplied via Firewire if that is available, but if not will default to the HD P2's own PSU or batteries. The HD P2 was certainly on and working. According to the manual its display should change to show a 'warning' that it is connected via Firewire and should not be switched off (or Firewire unplugged) until 'undocked' - by which I assume it means unmounted. But the HD P2 display simply showed the normal recorder status, etc. No sign it had detected being connected to a computer. Nor did the Shuttle show any sign of detecting or trying to mount the HD P2. I had thought that it might do this automatically as it does with, say, USB devices. When it didn't I wondered if there was an action I needed to take to tell Ubuntu to find the Firewire device and mount it. But I then couldn't find out about that. Looked in some of the books I have, and tried a few web searches. But I didn't come up with anything that shed light on using Firewire for connecting devices like this. Again IIUC the HD P2 manual correctly it should behave like a bog standard memory storage device. But I know essentially zero about Firewire as I've never used it before. My impression is that Firewire isn't used much, so I am wondering if the default Ubuntu install essentially ignores it. But I have no idea. Very likely I haven't made the right settings somewhere! :-) Slainte, Jim -- Please use the address on the audiomisc page if you wish to email me.
