bluetooth gamepad not recognized

I'm using rk3328 community build for my mvr9 box and I'm able to connect my bluetooth gen game s3 game pad, but it's not recognized in kodi.

I'm thankful for every hint.

Please provide a full debug log.

How to post a log (wiki)

Looks like the device is not recognized.

Code

It also looks like you may be having power issues. Try using a powered hub and see if this improves things.

Otherwise it may just be a issue with the rk3328 build which is always a possibility with such a new build.

It's a bluetooth controller, so no hub possible.

Do you have a hint how to dig deeper? As already mentioned, controller worked fine on rpi3.
