At least I have the dongle on a hub > located near the keyboard now so it is easy to reach :-). Is it the update, or is it the rebooting? Motherboards can always supply power to USB ports, or only power them while booted up, or only supply a tiny amount of power in standby mode (which may be enough to wake up a computer by pressing a key on a keyboard, but not enough to drive some hardware properly). There may be jumpers relating to USB power, or BIOS/UEFI settings about that. At switch on, or during the reboot power-on/off cycle, the USB port may be down, and not powered up quick enough. Perhaps it glitches coming on, and upsets the dongle. You could try setting a USB port to "always on." Alternatively, perhaps you need the opposite? So the USB port switches off then on again during a reboot, and resets the dongle. -- NB: All unexpected mail to my mailbox is automatically deleted.
