Hi hexdump, yesterday I tried the dev version 4.4.192, the camera worked, but there is no wifi and bt. can you make a new t9 dtb file for this kernel for us, Thanks.

Hi Hexdump, I installed balbes150's newest 4.4.154 image with your T9 dtb on my T9 box. it work very well including bluetooth^-^. I have a usb webcam from Fitipower integrated technoloy inc which works OK on my ubuntu 19.4 AMD computer, but it cannot work on T9. Using lsusb, it show this USB device with ID 18e3:5031, but there is no /dev/video(x) existing. Do I need to update the kernel to 5.x to fix this problem or modify dtb file on 4.4.154 kernel? thanks!
