bcm5974 doesn't work on MacBook 5.1

**larslarsson** · May 19th, 2009

Hi,

I have Intrepid on my MacBook 5.1 and most of the Mactel stuff works, but not bcm5974. I installed it from the dkms, and I did the fdi file thing and the usbhid blacklist (according to the threads here). bcm diagnostics says /proc/bus/input/devices: module NOT registered.

I'm running Ubuntu off of a USB stick, could it be that usbhid blacklist fails because of that?

I attach my /proc/bus/input/devices (added .txt). Can't find 'bcm' in it, should I? (If so, should I enter it manually?)

Thanks for any help!
Lars

is the module loaded?? (use 'lsmod')

**larslarsson** · May 19th, 2009

lsmod says:
.....
bcm5974 17032 0
....

So I guess it's loaded.

Thanks for the reply, but I have done the things described in that bug.
The only sure thing I know is that my /proc/bus/input/devices does not contain bcm5974.
Should/could it be added manually?
And may this have to do with my using USB (running off of a USB stick)? If I connect a USB mouse, it works fine.....

I really don't know, but you should post any relavant information to the bug report.

Did you make sure you updated your initramfs after blacklisting usbhid?

**larslarsson** · May 22nd, 2009

Good point, but I did do the update-initramfs.
(Including substituting the update-initramfs from the Live CD with the one from rofs.)

Does anyone know if the /proc/bus/input/devices file should have bcm5974 in it?
And if it should, in what part of install or boot should it be inserted?

Thanks,
Lars

The problem was obviously usbhid blocking bcm5974, I tried:
rmmod bcm5974; rmmod usbhid; modprobe bcm5974; modprobe usbhid
and then it worked. Just need to find out how to make it persistent.

Make sure you follow the instuctions on the Wiki for blacklisting usbhid and it should all work and be persistent - I'd guess you've probably just missed a step somewhere...
