> Hello,
>
> I just wrote a workaround for this bug. If you are concerned, you can
> test it. Please see the README file for more information.
>
> It works by loading the patched driver, sleeping two seconds, unloading
> it and loading the unpatched driver, simulating the reboot I did to work
> with my Bluetooth card.
>
> I still don't know why the patched driver don't work. I tested it in
> Mint, should work on Ubuntu, Debian or any derivative. It supports
> kernels 3.13, 3.19, 4.0, 4.1. Adding support for other kernel is
> relatively easy.
>
> Any comment is appreciated.
