I apologise if anyone has already asked this - I did look but could not see he same issue. I have an HP Spectre, bought December 2020. I upgraded to Windows 11 a couple of months ago. It has suddenly started to (repeatedly, every 20 seconds or so) ping and warn me that "the USB device is not recognised". There is nothing in the USB port. I tried Microsoft support: very helpful, but could not resolve. HP support: useless - I entered serial number and it said "wait" for a couple of hours before I killed it. I've uninstalled USB drivers and reinstalled them and also reinstalled W11. Clearly (?) a driver issue, but my solution at the moment is to plug in a dummy USB (the wireless mouse one), which shuts the thing up. If I need the USB I think it will work. Anyone know where I can get correctly working HP USB drivers? Is this a Windows error? (I'm thinking of rolling back to W10 and buying a Mac)
