@BDub, mainly bad news I am afraid.
Test environment: Parallels Virtual Machines under Macbook, loaded System firmware provided by yourself via PM.
Windows XP prior to installing the driver, Device Manager showed “Other devices” display just one line item, “Photon”.
Installed the latest Windows driver, three devices now showed up in Device Manager under “Other devices” - Photon Control Interface, Photon HID Mouse/Keyoard, Photon Serial. This is good!
Within Device Manager I click on each instance to see their properties. Device Status shows this:
This device is not configured correctly. (Code 1)
To reinstall the drivers for this device, click Reinstall Driver.
This is bad!
Windows 7 Problem is at the stage of loading the new Windows device driver, I browse to the very same directory as was used by Windows XP, but it complains “Windows could not find driver software for your device”.
This is also bad!
I have not raised a Github issue for this as am not sure where it should go…
