It's a generic firmware, but it's really old (pre 2.7.0.0). You should go to and get the latest one from there for your device (isl3887usb > 2.6.29). > I have copied these files (i tried cgwlusb200.arm also cgwlusb201.arm) to the following location on my Raspberry Pi: > > /lib/firmware/isl3887usb This should be the right location and filename for the firmware. > Sep 22 21:33:09 pinulldrei kernel: [1031466.202908] usb 1-1.2.1: New USB device found, idVendor=07aa, idProduct=0020 I can't find this device-id in the p54u_table.

Furthermore, In your case you should have seen something like this in dmesg: "wrong firmware, please get a firmware for "isl3887usb" and try again." > Everything looks fine - but no wlan0 device will be created :-( The led on the stick > will not turn on, so i think i have a driver problem. > > How can i debug / solve this problem?!? Looks like the firmware on the device crashed. You should physically disconnect and reconnect the stick before trying again. > Greetings from Germany, Regards from Germany, Christian
