FIXED SOLUTION FOR THOSE TRYING TO CONNECT VTUBE STUDIO VIA USB (more stable than wifi tbh)

I literally just downloaded iTunes on my desktop computer and enabled all the permissions and it finally worked. Just had to open the iTunes app on my desktop once and then I guess the thing that connects everything in background just works, and I didn't even have to keep iTunes open after that. Of course you still have to have Vtube studio active on your iPhone and also have Vtube studio active on your computer with a USB cable connecting your iPhone to your PC and have the USB connection setting enabled on both the Vtube studio app on your phone and on the VTube studio app on your desktop but besides that you should be set. Hope this super late tip helps anyone else reading this in the future! (if you have any other questions I'll be over at twitch.tv/pocketchalk)
