Hi, have you checked your desktop for Win 10 compatibility?
Windows 10 Upgrade
Windows 10 Update

I can't find it on either of these.

That -er- small point aside, you may have an outside chance of finding a driver using, say, Drivermax (free for 2 drivers a day).

In device manager, for that item you are having an issue with:

Right click, properties, then the details tab.

Select Hardware ID's and copy all that below that appears here. I believe there may be more than one that we can search for ... worth a shot anyways ...

Do a scan with Drivermax- pretty quick. You might be lucky- it's found me two I needed and didn't get/couldn't find for devices otherwise.
