How to test a firewire 400 port

New iMac 24" with Leopard and iMovie 08. All updates have been loaded.

iMovie will not import from Canon ZR500 DV camcorder. iMovie recognizes the camera, can control the camera (rewind) etc. but preview doesn't work and no data is received.

Camera works fine with my Windows XP machine and Adobe Premiere 3.0. It also imports fine with the Apple store's iMac. The problem also existed when I had Tiger 10.4.11 loaded.

I just tried a demo version of iDive and it does exactly the same thing as iMovie (recognizes and controls camera but no data imported).

Changed firewire cable, but no joy.

Looks like it's the Firewire 400 port that's the culprit. The 800 port is fine (driving LaCie disk).

Any way to test the Firewire 400 port? Update firmware, drivers, etc.?

iMAC 24", Mac OS X (10.4.10), 500 GB drive

Sounds like a plan, a hub is it.

Thanks all

Hi there. Related to this thread, I am having probs with both my 400 and 800 Firewire ports on my new iMac Intel 24". I am trying to connect an old Porsche LaCie drive and an M-Powered Firewire 410 audio hardware box. Both were working fine but now neither are connecting successfully. I've tried resetting the PRAM, shutting down, unplugging/replugging.... nothing seems to work. Any thoughts out there? Thanx!
