Windows 10 "other device" HP Stream 11

I updated my HP Stream 11 to Windows 10 using a clean installation, after creating an image of 8.1 with Macrium.

Windows 10 installed well, for the most part, but the Device Manager shows several "other devices" for which Windows cannot find drivers on the web or the C drive. I have no idea what these devices are, and running all of the HP driver update apps (from their website) but these devices remain unknown and driver-less.

When I run a search on the web I come up with "driver update" services, but offers like this often end up causing more problems than they solve.

NOTE: I know some people have had trouble getting the HP Stream trackpad to work with 10. I don't have this problem running Windows, but it doesn't work in the Macrium rescue media I created, so something is missing.

I know this is a long shot, but I'm wondering if anyone here has done the upgrade on this model and found all the needed drivers satisfactorily. I expect I can restore the 8.1 image and get drivers there, but I'd rather not do that if I don't have to.

Thanks in advance.

My suggestion is to go to Device Manager and Delete all "Unknown Devices" and reboot.
See if then they get automatically properly installed.
If not, go again to Device Manager and Scan for Hardware Changes.
If there are still "unknown Devices", then there is missing Drivers for that Hardware.
