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. > > does modporbe emit any errors and what does 'dmesg' or /var/log/messages > > show?

Let me know where this > log resides and I can include that too. 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.
