HV40 connection issues

I am following the recommended 2 camera configuration… Mac book pro… Sonnet expressCard for additional FireWire bus… Two freshly new, out of the box, canon hv40s… Both cameras setup exactly the same way, menu for menu item…
Camera 1. Works great… Camera 2 is not recognized by BTV. I have tried isolating the cable, the port, seemingly everything to no avail…camera 1 works by itself in either the sonnet card 6 pin FireWire port or the 9 pin fw port on the MBP. When I substitute cam 2 for cam 1, it is not recognized.

Thoughts?

Well… I changed the cable… and everything works… yikes… didn’t think that would be the problem… still a puzzlement…

Thanks for getting back to us with the solution.
