Comment 6 for bug 434007

Confirmed here as well. I'm running the latest release of 9.10 amd64 as of the date of this post. I'm also using a mighty mouse, which works fine. Here's the dmesg output on startup. You'll notice that I reconnect the keyboard using bluetooth preferences to get it working.

The error seems to occur here, but I haven't been able to track down that error number:
[ 30.816466] apple 0005:05AC:022C.0002: parse failed
[ 30.816473] apple: probe of 0005:05AC:022C.0002 failed with error -14

To all who have posted, could you post the output of:
$ dmesg | grep apple
to see if we're all getting the same error?
