Venus OS v2.73 or v2.80~24 RPi 4 B & Official Touch 7": USB and Touch not working

Hi,


For some reason touch (and dimming) isn't working for my official 7" touch screen. RPi4 doesn't either detect if I plug a USB drive in any of the ports (including port in touchscreen).

It seems that /sys/class/backlight/ is empty directory. What could cause these?

The issue is with the kernel and the new RPi4. Older one seems to be working.
