This is the case: Bqeel M9C Max [S905X/2G/16G] , Kodi Matrix installed on internal memory. All its fine except the fact I can’t use the usb port next to the sd card slot for keyboard or remotes. I have power on that port all the time (box on stand-by or powered up). When ATV experience ROM was installed on the nand I could use both ports, on Coreelec I can’t (doesnt matter what version). I use one usb port for ethernet adapter and one for an Minix Neo A2 lite remote.
I believe my case is similar with this no usb.
I tried to upgrade to nightlines or downgrade to 9.2.6 but no change, could you help me with an updated dtb?
