Same issue here with my Corsair Schmitar RGB Moba mouse. Intermittently wont power up. Keyboard, Gamepad etc are all fine on USB, just the Corsair Mouse has this issue. I thought it may have been my older I7 motherboard but I've just upgraded and gone from Intel to Ryzen so Motherboard, CPU and Ram have all been changed. I also did a full reformat of Windows 10 when I upgraded all my internals. Very frustrating.
