Qualcomm mcp100 can't input/frozen

Other than disconnecting the power cable to the black box there's another way to "warm boot" a Qualcomm. Select Settings then slept Speaker. Change the speaker setting.

It will then have a pop up menu telling you this will require a system reboot and ask if you want to "Apply". Select "Apply" and this should fix the issues. With Swift's setup this could be done with the wheels turning only if you are logged in as a team. It takes a few minutes for the system reboot.

 

Go buy a wireless keyboard if it was a usb port like the mcp50. You'll like having a separate keyboard anyway.

 

Qualcomm is a bad system. It came from the 90s and it should have stayed there. I've always had problems with it.
