Here's what I got... #lspci -n | grep -i '00:1b,0' 00:1b:0 0403: 8086:3b56 (rev06) #grep '8086' /lib/modules/*/modules.alias | grep -i '3b56' No output from the above The test on the other device #lspci -n | grep -i '01:00.1' 01:00.1 0403: 10de:0be2 (rev a1) #grep '10de' /lib/modules/*/modules.alias | grep -i '0be2' No output from the above.
