I'm having trouble getting the wlan0 interface to show up for a Marvell
8797 USB to WiFi chip, and it seems like everything should be working. I'm
running Arch Linux Arm, 3.8.13 kernel, and have verified that the modules
are loaded correctly, and that it recognizes the device, but still no wlan0
interface. I also verified that the firmware is indeed in the
/lib/firmware/mrvl/ directory. Am I missing something obvious?
Here is my output from dmesg, lsmod, and modinfo.
