WLAN driver not loaded by bone

Hi,

On my bone i am running the Ubuntu demo image.
When I plug in my wireless dwa-127 dongle nothing really happens.
Dmesg does show a USB device found and that it is a ralink
manufacturer but nothing is said about any driver being loaded. It
should be able to use the rt2800usb driver that as far as I can tell
is available in the image.
If I try to insmod this driver I get a lot of complaints in dmesg
about unknown symbols from rt2800usb.
It should also be able to use rt2870sta driver but this driver does
not seem to be available in the image. I could try to build it.

Does anyone know how to get Ubuntu to load the driver?

That's normal when you ismod that module directly..

use "sudo modprobe -v rt2800usb" to see what you forgot to load first..

It should also be able to use rt2870sta driver but this driver does
not seem to be available in the image. I could try to build it.

rt2870sta was ripped out of the mainline tree in the 3.0-rc cycle..

Does anyone know how to get Ubuntu to load the driver?

Another thing, what's the vid/pid of the dongle? just dump 'lsusb'

Thanks a lot for your answer

Nah, why wait.. :wink:

I will give it a go and see if I can figure it out. First time I
compile a kernel and even change a kernel.
One thing though can I do this on the bone? I hate cross compiling :slight_smile:

Sure, but it'll take a little over 2G of space on your bone, and
around 5-6 hours..

No problem thanks a lot

Just out of curiosity. Is the problem simply that the kernel does know
what driver to use based on those vid/pid values?

exactly... with usb drivers, there's a way to force a specific one,
but my google searching hasn't turned it up..

btw, i built up the uImage/modules, you can grab them here:
http://rcn-ee.homeip.net:81/testing/beaglebone/3.2-D-Link-DWA-127/

That is very kind of you I am looking forward to try this.
Is it just a matter of copying these to the right place on the sd?

Yeap, copy the *.uImage as "uImage" in your fat partition, and extract
the modules to the rootfs partition, like:

sudo tar xfv *-modules.tar.gz -C /media/rootfs/

This works great thank you very much.
Both normal an ad-hoc connections works great and master mode to use
it as an access point works almost perfect :slight_smile:
