hey there
I am new to linux so i may say some mistake
u have to check if the kernel loaded your driver with this command :
ls /lib/modules/*/kernel/drivers/net
do you see anything that can be your driver ? (like)Creative Labs SB X-Fi
If yes : /sbin/modprobe nameofurdriver
If no : I don't know how to recompile the kernel (i need to know too , check on my post i have the same problem with my Eth0 inf)
Glad if i could help
