Usb type A and type c conflict

Hi, just got my 960 which also happens to be my first 96board.
I am having an issue in the AOSP build that came pre-installed, build 98 and also 120
when i connect my mouse/keyboard to the usb A ports, I am able to use them fine but as soon as I plug the type-c port to my desktop for adb I am no longer able to use the usb mouse and keyboard. ADB works fine though.
I am well aware that the AOPS o-preview branch that comes pre installed is still very much under development, just wanted to know if anyone is facing the same issue?
thanks
