Just to check, what does "uname -a" tell you?

I really thought that I had this fixed, but don't have the right Pi to test it on (I have 5 other models of Pi..)

I can't figure out "uname -a" after install the realtime kernel, because I can't control RPI4 without a keyboard and mouse. Once the USB breaks I have to start with a new image.

Or do you want "uname -a" before install the realtime kernel?

I lost all my work before this update. Fortunately, I didn't do anything important at RPI.

I'm not a IT technik. I'm not a programmer. I am beginner.

If you want to test my hardware remotely this is not a problem. But I need to know what to do.

Get the Raspberry Pi Imager for a (non Pi) computer of your choice and install the standard Raspberry Pi OS.
www.raspberrypi.org/software/

Then try "sudo rpi-eeprom-update" and paste the result here.

Then you can try installing the realtime kernel, and see if USB still works.

Can those with this problem please state exactly which model of Pi they are using?

One possible problem is that the 8GB Pi needs a 64bit kernel if it is going to address more than 4GB.
