Hello, it is good to hear that the HDMI to HDMI combo is now working.
You are asking if a mouse and keyboard can be recognized after the Desktop container has been started ... no this is not possible and I explain you why. When a Docker Container is started then exactly at this time Docker makes a copy of all the recognized USB devices connected and makes them present in the container. It is a kind of freeze frame and even if you would connect mouse and keyboard aftewards the freeze frame in the containes isn't change any more. Of course in the Linux Host OS they are recognized ... but this information is not forwarded to the container. The readme file of the container tells you about this circumstance in one sentence.
It is the same like the graphics controller chip of the Raspberry Pi CPU recognizes a HDMI communication only at power on state once. If you would connect a HDMI cable after this recognition time, the HDMI port is remaining disable and is just black
Thx
Armin
