Any good alternatives to VirtualHere?

I'll start by saying that there's nothing wrong with how VirtualHere functions. I have used it for a couple years on my nvidia shield while streaming games from my pc and it's perfect for what I need. The problem I have encountered is that I'm no longer using the shield and have transitioned my entire setup to use a raspberry pi 4 instead because the shields wifi becoming more unstable with every update nvidia pushes.

I would love to continue just using VirtualHere, but I've just learned that the developer does not allow a license transfer for any reason so my $50 license is completely useless now that the shield is gone. Knowing that the license is non-transferable makes me unlikely to ever spend money on it again because I cannot guarantee how long these devices will last and $50 is far too steep for a single device private use license on any software. My primary use case is with a moonlight/sunshine setup which can handle the controller inputs just fine after a little bit of input file tinkering.

The things I absolutely cannot figure out how to make work without VirtualHere is a Dolphin bar that is used for Wii/WiiU games and the gamecube controller to usb adapters. I've seen people mention using usbip, but I haven't been able to find any reasonable explanation or documentation on how to actually use usbip without fully configuring it every time the device reboots.

I'm not against the idea of a more manual setup. I just need something that once it's configured will allow passthrough of any usb device from a raspberry pi to a windows machine and not charge me a fortune every time I need to swap hardware in the future. I'd be willing to pay for similar software if it was a little more reasonably priced for what I'm doing.
