My logi wireless keyboard/dongle works to get into the bios. So there would not appear to be any driver needed to operate it, so that would make me suspect the reboot is more of the cause than anything else.
And usb chipsets/connections in my experience aren't the most reliable devices depending on the chipset/usb power/cabling/other misbehaving devices on the bus with it.

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.
