Receiving "socket.error: [Errno 107] Transport endpoint is not connected" on SteamOS

I am using a brand new DualShock 4 controller and my motherboard's built in Bluetooth (not a plug-in dongle). By simply pairing the DS4 controller in the Linux desktop, I can get very basic functionality. I would like to use the touchpad and mouse emulation and to the best of my knowledge, ds4drv is the only way to do that.

When trying to connect my DS4 controller using ds4drv, I receive the Errno 107 "Transport endpoint is not connected'. I am using the SteamOS Beta branch with Bluez 5.36.

Correct me if I am wrong but based on the documentation, it would appear ds4drv has never been tested without using a plug-in dongle.

Just came across this - https://github.com/chrippa/ds4drv/wiki/Bluetooth%20dongle%20compatibility

I am willing to bet that the onboard bluetooth controller built onto my motherboard isn't compatible. Bummer. I'm not going to troubleshoot this any further.
