Thanks, Dell Support for contacting me so quickly. I deleted the drivers and all my USB devices are working well after a restart.
XPS 8930, Windows 10 Pro I think I know the answer to this, but I want to confirm. I copied my old HP computer to my Dell XPS 8930 using PCMover.  Windows Update keeps wanting to install updates to HP Universal Serial Bus Controllers. I used pnputil and the drivers show up in an enumerated list of 3rd-party drivers. (hpbuio140l.inf and hpbuio160l.inf)  As far as I can tell, they don't show up in Device Manager. I'm assuming they're just an artifact from my old HP desktop.  So, my question: is it safe to use pnputil to delete these HP drivers? Thanks for any help!
