Debian + IVTV 0.7 + udev = firmware issues


Okay, so I've seen postings all over the internet about the infamous

Quote:
ivtv0: unable to open firmware v4l-cx2341x-enc.fw
error messages that seem to keep popping up in IVTV installations, and over the past month I've followed each and every one of these and come up with nothing. Here's my data
kernel version: 2.6.17.6
ivtv version : 0.7
dmesg | grep ivtv :

/lib/udev/hotplug.functions contains the following line: FIRMWARE_DIRS='/lib/firmware /usr/local/lib/firmware /usr/lib/hotplug/firmware'

/lib/udev/firmware.agent loads /lib/udev/hotplug.functions

When udev's logging is set to "debug", running `modprobe ivtv` dumps the following data into /var/log/syslog (the output is actually about 230 lines, but I've shorted it quite a bit):

The file /proc/sys/kernel/hotplug is empty and any attempts to put anything in there lead to permission denied errors (even as root)

I have copied the firmware files into /lib/firmware, /usr/local/lib/firmware, and /usr/lib/hotplug/firmware and given them all 777 permissions (more out of frustration than actually thinking it would help).

As best as I can tell, /lib/udev/firmware.agent is never getting read by anything and I can't figure out why. I tried to give as much information as the LQ forum would allow, but I'm sure I left out 2 or 3 pieces of key information. I've been struggling with this on and off for over a month now and have made no progress, so I'm really at my wits end right now. After living with MythTV for the past 3 years or so, not having it is like torture!

Any suggestions/ideas/tips would be GREATLY appreciated!!
