So we have about 20 new Windows 10 machines in a training room, all small form factor HP somethings, I'll get the exact model number later
HP 8200 Elite Small Form Factor PCs. On any given day when they're all freshly booted up, about half will fail to recognize that a mouse is plugged in. No rhyme or reason that I can see, a pc that booted fine yesterday may not see a mouse upon bootup today. Just unplugging then plugging the mouse back in causes the mouse to be recognized. As this is a training room we really don't want folks to have to fiddle around under the desks.
Drivers are fully updated, Windows is fully updated. These all came with 10 installed, they weren't upgraded from 7 or 8. Googling the problem gives a metric ton of unrelated issues, mostly dealing with mice not working after an upgrade.
Any ideas? TIA
