[mythtv-users] Firewire in CentOS 5.2 on GA-MA78GM-S2H (Texas Instruments TSB43AB23 chipset) - plugreport shows nothing

[kanetse@gmail.com]

Trying to get firewire working with my mythtv-backend.  Previously,
the same cable box (Motorola DCT6416) was working fine with an older
backend with a VIA-based firewire card in Fedora 8.

On my new setup, running CentOS 5.2, plugreport is showing nothing.
When I run it (as root), it just exits back to the prompt with no
output whatsoever.  However, if I look in dmesg, I can see the
firewire card is initialized.  Modules are loaded properly, the OS can
see and probe the firewire chipset on the motherboard, and it can even
pull off the node id of my firewire cable box.

Motherboard: Gigabyte GA-MA78GM-S2H
Firewire chipset (on motherboard): Texas Instruments TSB43AB23
IEEE-1394a-2000 Controller (PHY/Link)

Kernel: 2.6.18-92.1.10.el5.centos.plus

I've tried plugging it into both firewire ports on the cable box, same
thing happens.

Any ideas?

Thanks!
