Hi,

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.

Our linux is using the 2.6.35.7 kernel version.

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!
