I have a RockPi 4B
I noticed that following a reboot (cold or hot), sometimes the USB devices plugged into the USB port does not work any more. lsusb shows that no devices are connected to the port. To get it working I need to un-plug and re-plug the USB device, which always works after the system boots. But if I leave the device plugged in, even if I reboot many times, it may or may not connect.
I am using Debian 11, with https://radxa-repo.github.io/bsp/ compiled latest u-boot and stable linux headers.
I applied u-boot-latest_2023.10-1_arm64.deb and the linux stable .deb files.
Can anyone tell me why, and how can I reset the port / USB hub controller programmatically?
