Useful huh? I wondered which device driver was the cause of concern. In my ignorance I thought that if I clicked on the button marked, helpfully, 'learn more' then I would indeed learn more. But no. The aforesaid click opened up a standard Microsoft web page with a search bar. A blank bar. It did not even have 'device driver problem' or similar pre-inserted. Having told me I could learn more, it did the equivalent of a taxi driver picking up someone at Heathrow who asks for "central London, please driver" and dropping them off in Slough near the station.
So I have no idea which device has incurred the wrath of the backroom boffins and if they want to play the game of alarming me for no obvious reason, I'm damned if I'm going to play along.
I had just done a backup to my USB 3.0 flash drive, which appears to be working perfectly well, but presumably Windows is capable of identifying it more intelligently than by the useless word "device". Or is it?
