I just tried to use the scanner on my Epson ET-4500 printer, only for the system to inform me that the scanner was not connected. Strange, as I had just used the printer. So- shut everything down, check connections and bypass the USB hub and connect directly to the computer. Fire everything back up, but still no scanner. I then remembered that I had a windows update two days ago. Removed this (KB5022834), rebooted and scanner now working. Why do Microsoft keep trying to sabotage my computer?
