100% CPU usage

[zaidakram]

I believe this issue is still not resolved. My kernel version is:

Linux Zaid-PC 3.13.0-30-generic #54-Ubuntu SMP Mon Jun 9 22:45:01 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Yes, I can confirm this issue is still present. However I didn't wrote this driver, I just modify the official driver to solve some problem (bluetooth not recognized, don't work on kernel 3.16...) with solution found on forum... If you can find a solution on the internet I would be happy to add it here !

Maybe we could write to Mediatek, if enough people ask for a fully workable driver we may have one.

Yeah, Just read on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1220146 bug report that someone wasn't having 100% CPU load with your code, so I figured I might give it a try as well.

[zaidakram]

I'm writing them every day. Lets hope it annoys them soon and they make this crap stable...

[tobiasBora]

Ahah tell me if you have any result !

[zaidakram]

sure thing!!
