To Reproduce

`Unhandled Exception:

System.DllNotFoundException: libusb-1.0 library not found. This is often an indication that libusb-1.0 was installed to '/usr/local/lib' and mono.net is not looking for it there. To resolve this, add the path '/usr/local/lib' to '/etc/ld.so.conf' and run 'ldconfig' as root.

Expected behavior
Expected for the program to at least load, even if it may not be able to see the console.

Screenshots
No screenshots, see listed crash error.

Additional context
Tried copying libusb-1.0.so.0 to a dll file, but no dice.

Did you install libusb Linux package?

[NightSprinter]

I do in fact have it installed. I ended up going nuclear on installing by just "sudo apt install libusb*", and it's going. Just dunno what of the LibUSB packages it was missing that was required.
