<< You guys have to understand that the 4 port USB hub found on the GTXP's breakout box is for gaming perihperals; therefore, the USB ports are UNPOWERED. So, if you're plugging in a mouse, keyboard, or gamepads, you'll be fine. If you're plugging a scanner or printer to it.... >>
not sure this is correct - my scanner has seperate power supply, don't think it needs power from usb. on the other hand, my webcam which does need power works just fine on usb3 but not on usb4 (nothing seems to work on this port).
oh, wait ... i think i'm being dumb. the webcam/mouse/etc are obviously pulling power from the usb port since they don't have their own power supply. so what exactly does UNPOWERED mean? that the ports are only for unpowered devices? can someone explain to me how that works - how an unpowered device would work but a powered one wouldn't?
