I have a desktop that all the USB ports work but only with devices that have their own power. Any non powered device like a mouse, keyboard, or flash drive will not work. Devices like printers and external hard drives that have power will work. Help !
Does that include the USB ports on the back of the computer (that are connected directly to the mb)?
All the USB ports both front and back only work with powered devices. Anything that doesn't have power like mouse, keyboard, or flash drive will not work. Interesting part is that I have this computer to a USB KVM switch with another computer. The KVM switch must be only getting power from that other PC because if I shut down that computer then I cant use this one because the KVM switch loses power.
