I've had a Glyph firewire HD for many months with no problems. I have now
tried to incorporate a Canopus firewire video capture box into my setup.
As soon as I try to have them both available on my desktop (PC not a Mac),
the HD icon disappears. The Canopus by itself and the HD by itself work flawlessly, but not together. Can anyone tell me what is happening?
the principle of firewire is that up to 64 devices can share a (serial) bus and each device *tells* the bus how much bandwith it would like to get. video (and audio) devices are often suggesting 100% bandwidth (since they are kind of realtime applications) and if the FW-controller is allowing this it's highly probable that another device on the bus (with lower priority) looses the minimum needed contact - and gets disconnected.
a possible solution would be to add another FW controller to the system and have HD and video on two seperate busses (and i mean _busses_ not _plugs_)
