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..)

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.don't have the right Pi to test it on (I have 5 other models of Pi..)

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.

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.

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