Then I realized the secret: The Quantum QHM74872VC doesn't need a custom driver. Many games released after 2015 (e
It is lying to you. When Windows says "Driver not found," it’s actually wrong.
This gamepad uses the Standard Microsoft USB HID (Human Interface Device) protocol. It is dressed up like a fancy proprietary controller, but underneath the plastic, it speaks the same language as a $5 generic SNES knockoff.
