Dear Greg,

This was my original message:

We bought two PCIe serial cards from LAVA, one dual and one quad port card.

My problem is that the devices are visible in lspci, but no module
is loaded to the cards. I have other PCI card from this manufacturer
and they are working well and the necessary module is loaded fine. I
can't use these cards because of this problem.

Our linux is using the 2.6.35.7 kernel version. I checked the source
code and the cards are already there in the necessary c files.

If the device ids are in the driver for this device, are you sure the
driver is loaded?

What driver should be controlling it?

Could you help me to fix these card?

I attached the output of the dmesg and the lspci to my mail.

Thank you very much!

This doesn't look like your PCI devices above, as the pci device bus
numbers don't match.

Can you provide the output of:
	lspci -n
	lspci
	lspci -k
for us?

as well as the full boot log?

thanks,
