Error code 12 workaround / fix for (TB3->TB2) eGPU on 2015 MBP 15" (might work with other MBPs) !!

This workaround might work for other MBPs but I have not tested it on anything but my 2015 MBP 15".  I am running Windows 10 Pro Build 1903 with no updates, a Razer Core X, and a Radeon VII.

If you are using a device other than a 2015 MBP 15", you may need to modify the driver IDs in the script.  All this does is repeatedly toggle on and off your eGPU PCIe controller until error 12 is resolved.

Hope that my script helps some of you struggling with resolving this issue! Smile

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
