Re: How to git and build HVR-2200 drivers from Kernel labs ?

Only Steven can look at the schematic and know for sure what prompted
them to update to a new PCI ID.  However, you can definitely try doing
"card=4" and see if it works.

Card=9 won't work since that card number is not valid given the card
list in your driver.
