Anyone that works with the dtb images, it should be.
I have giving dmesg logs of USB activity under both Android 9 that has the two functional USB ports, and CoreELEC that only one functional USB port, the USBv3 that’s a host. Available at Beelink GT1 Mini & CoreELEC, No USBv2 Port
USB-OTA (USBv2) port on this GT1 Mini needs to also act as a host too, or do dual-roles and It’s not. From my research, It’s all controlled via dtb image file.
So GT1 Mini users and alike shares such a problem, you can’t use USB-OTG port to install CoreELEC. You have to use another port, and in my case GT1 Mini only has one other USB port and we need to be able to use Keyboard to configure CoreELEC and also operate Kodi. Need to use an USB Hub, also once CoreELEC is installed via USB, the USB-OTG port still remains unusable… Using USB over SD Card does nothing to address the non-functional USB-OTG port under CoreELEC.
