I start playing with a Compute Module 4 with the idea at one time to have my own STB for cable TV (and maybe satellite). For tuner tv a have two choices, xbox tuner or a pcie TBS tuner.
I install last stable image, it is working (without dts-hd and stuff), it is fine for the moment.
I need to enable usb, in CM4 is disable by default, I have to add dtoverlay=dwc2,dr_mode=host in config.txt.
It not works, probably because missing the right dtb.
My question is if there is any plan to add CM4 to the list of Rpi.
