Last update of LinuxCNC Raspberry Pi4 USB does not work

Hello,

I used several month Pi4 + LinuxCNC + Mesa 7i96. All time it was working. I install image from here:
www.linuxcnc.org/iso/linuxcnc-2.8.0-pi4.zip

But the last update kill USB on RPI. RPI booted, but with out mouse and key I should only look on monitor. So, I had to make new image for SD card. It work again. I made "sudo apt-get update, upgrade" and after reboot the USB was killed again. I tried it several times.

I tried install:
downloads.raspberrypi.org/raspios_arm64/...os_arm64-2020-08-24/
USB worked. I tried reboot RPI several times and USB worked.
I tried install LinuxCNC:
linuxcnc.org/docs/2.8/html/getting-start...lling_on_raspbian_10
after reboot the RPI does not boot the system at all.

Can I ask anybodyfor help?

I'm sorry, I didn't mean to be rude. I am from the Czech Republic and my English is very bad.

Oh well we can blame google for that then !

Mám se dobře, děkuji za optání. Jak se máte vy? Setkal jste se někdy ve svém životě s češtinou, nebo s Českou Republikou?

Jsem byl v cheskou, nejvic v Brne!

A líbilo se Vám u nás? Jak dlouho jste u nás byl?

Klidně tohle vlákno můžete smazat, ať nedělá zde na fóru nepořádek.
Děkuji
