Hello. Please apologise the "noise" information above... I have managed to reproduce it again, but now at least I have the root cause. It goes like this:
1. Normal boot up (either from the internal HDD or from the usb stick Kubuntu Live Session) 2. Mount the usb stick and then unmount (get the "Safely remove" message, but do NOT remove the stick from the usb) 3. Restart the laptop (let it boot-up using the internal HDD) Expected: next session should recognize USB devices (even if it won't "see" the device I left in the USB, it should at least detect its removal or other new devices) Actual: rebooting with the USB device still plugged in (after the "safely remove" message) somehow disables all the USB ports of the laptop; no matter if I remove the device afterwards, the USB ports activity no longer gets detected until another reboot. So it has nothing to do with updates, please ignore my babbling on the matter. If you cannot reproduce this issue or you need more information on my part, please let me know.
