Windows has a scan app ( ms-windows-store://pdp/?ProductId=9wzdncrfj3pv ) that can commandeer a scanner connected via USB even if the scanner's own software doesn't let you. Not sure it works with every model, and it's not very rich in features, but I've successfully thrown it at two scanners that I couldn't get any use of otherwise.

The generic Linux scan app wasn't able to scan until I replaced the ink in a Canon device.
