Now it works only if connected directly to the PC.

The keyboard itself has an USB hub incorporated (apart from this it is absolutely generic one).
Once I was able to get it working through the KVM - I booted up with the keyboard in the PC directly and then plugged it in the KVM and it worked.
After restart worked again.
After second restart it didn't. And it is like this ever since.
The keyboard still works on the other machine on the KVM - not upgraded Ubuntu.
The keyboard works during boot and for GRUB. It stops once the Ubuntu login screen is displayed.
Ideas will be greatly appreciated.
Thanks in advance!
