Micro projector question - worth it to get the VGA?

So I bought a micro projector awhile back and its become quite annoying to connect via usb every time I want to load new files on to my projector but at the same time, connecting my laptop to projector is probably just as much of a hassle..

I’m thinking about upgrading my model to VGA while i’m still within my return/upgrade period and taking the small hit for restocking just to have that extra capability.

Does anyone know of a software that will either project my desktop image or dual monitor through usb for an aaxa m1 micro projector?

specs:
AAXA M1 Micro Projector - LCoS Hand-held Mini Projector - LED Pocket Projector

right now I’m just doing slides for my presentations:
