Rpi CM4 LibreElec USB not work

I'm trying to run LibreElec on my new Rpi CM4 with the official mainboard. The system is lounching, but USB A doesn't work and I can't use mouse/keyboard to control the system. I tried to enable USB by adding a line to config.txt, but without any changes. What can I do with it?

dtoverlay=dwc2,dr_mode=host

The solution is add otg_mode=1 at the end of config.exe https://github.com/LibreELEC/L…22#issuecomment-739526268
