Camera and scanner are 2 different things.
Twain,exe is in GIMP for the Microsoft's Windows OS, AFAIK it's an old 32-bit application/plugin for scanner only!, Not cameras, but scanners.
You cannot tether from a camera to GIMP directly because GIMP cannot find a connected camera.
Roughly, If GIMP can find some scanners via twain.exe, GIMP was not made to find cameras and twain is not made either to find a camera.
