Problem has occurred since the October upgrade of Windows 10.I have a Trust powered external USB hub driving my keyboard, external hard drive, webcam and printer.My wireless mouse sensor is plugged into a front USB socket on the PC. That works.When I start up I get the sign-in screen, but the keyboard does not work, so I have to restart, whereupon the keyboard and everything else on the Trust hub works.I have tried out a suggestion of disabling USB power-saving, but it did not have any effect so I have restored USB power-saving.Your suggestions would be appreciated.
