Ok, have you a device who indicate you have power to the usb ports ?
I'm not sure exactly what you meant, but I'm assuming you meant to ask if I have a device that will tell me if my USB ports recieve power. In that case, I do not.
However, when I plug in my USB mouse, the laser part of it will light up and stay lit, indicating that it is receiving power. When I move my thumb over the laser part of the mouse it lights up brighter, meaning that it senses something. Also since my computer detects something was plugged in, I would assume that the USB ports work. It's just that the drivers won't install, and it says unknown USB device.
