Bluetooth dongle DB-120 / kext problems

[lemmyc]

I updated to Mountain Lion and my D-Link DB-120 Bluetooth dongle has been working intermittently.

 

It was working at first, then stopped. Then started working again - now not.  I think the changes are to do with the way I've been loading kexts. I was experimenting with the Lion bluetooth kexts in an attempt to fix things.

 

Now I've moved all my kexts to S/L/E and rebuilt the kernel cache. I'm using the Mountain Lion bluetooth kexts. The Bluetooth dongle is not properly recognised:

If I use the Lion bluetooth kexts, the dongle is recognised correctly. But when I do

 

sudo kextcache -prelinked-kernel

 

to rebuild the kernel cache, there is an error with the AppleHIDMouse kext, and I guess this is why my Magic Mouse is not detected. There is also an error if I use the Lion AppleHIDMouse.kext

 

Any suggestions?  Other people seem to have this dongle working in ML OK...

Thanks.

OK, I found this post which describes my symptoms exactly.

Setting ControllerPowerState to 1 as described fixed the bluetooth dongle:
