This repo should be OK for getting over initial problems (but it has a
buffering change that I probably won't ask to be pulled).  I would
however encourage you to use the main repo at

http://linuxtv.org/hg/v4l-dvb

or this one which has a patch to improve reliability for some older
systems:

http://linuxtv.org/hg/~awalls/cx18-mmio-fixes

Maybe, but not likely.

OK.  Let me ask some basic questions that you may have already verified:


1.  Does the following command show a cx18.ko module installed?

$ find /lib/modules -name cx18.ko -print



2. Does this command:

$ /sbin/lspci -vv

show a

"Multimedia video controller: Conexant CX23418 Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast Audio Decoder
Subsystem: Hauppauge computer works Inc. Unknown device 7444"

?


3. Have you installed the firmware from this archive:

http://dl.ivtvdriver.org/ivtv/firmware/cx18-firmware.tar.gz

into the proper directory (e.g. /lib/firmware) for your distribution?



4.  When you perform these commands as root:

# modprobe -r cx18
# modprobe cx18 debug=3

does modporbe emit any errors and what does 'dmesg' or /var/log/messages
show?  (Please don't grep on cx18, as not all relevant messages will
have cx18 in them.)


5.  When the module is loaded, it should always blurt out at least
"cx18:  Start initialization, version 1.0.0" in dmesg and messages,
unless the kernel couldn't load the module.  If the kernel couldn't load
the module, it should log an error message: what is that message?


> Also, I get the errors when running make unload:
> loudestnoise@loudestnoise-desktop:~/v4l-dvb-fc3285e4b3fa$ sudo make  
> unload

I wouldn't worry about those.  I get them too.  As long as lsmod shows
the modules have been unloaded, you're fine.

Andy

Well, if lspci can't see the card, no amount of mucking with the cx18
driver is going to help.

See if

$ /sbin/lspci -n

returns something with "14f1:5b7a" which is the PCI vendor and device id
for a Conexant CX23418, like this:

03:03.0 0400: 14f1:5b7a

or a number that is very close (maybe wrong in one or two bit
positions).

If it doesn't show at all, invoke lspci as root to in mapping mode
(dangerous, according to the man page) to see if it finds the device: 

# lspci -n -H1 -M

Otherwise, you'll have to take other measures (pulling cards, moving
into a different slot, etc.) to see if you can get the board recognized
by the PCI subsystem.

If a PCI ID that is close, but wrong in a bit position or two, shows up,
then pull the card, blow the dust out of the slot, put the card back in
the machine, and try again.

The cx18 driver loaded up, the PCI bus was scanned for matching devices,
and none were found apparently.  No errors, but also no card with the
proper PCI ID visible on your PCI bus.

More of the same.

No. There shouldn't be an error from the kernel in this case (but it
would be in dmesg), as the module loaded properly and blurted out "Start
initialization, version 1.0.0".  The PCI subsystem doesn't appear to be
recognizing your hardware.  That is not an error condition from the
perspective of the kernel nor the cx18 driver per se, but it certainly
is a problem.

Well since lspci -v still doesn't recognize my HVR-1600 after
switching around card positions and even removing my other tuner card
should I assume I have a bum card?

It's a strong indication that it's bad.  If possible, you may also wish
to try it in a different system just to be sure.

Try it in anther PC, or perhaps your neighbors, make sure this isn't 
power/supply and/or motherboard related.

After this call Hauppauge tech support.
