Most of my USB devices work in my USB 2.0 ports. All of the devices that are externally powered work, i.e. external Hard Drive enclosure, printer. Some devices that aren't externally powered work as well, i.e. USB Flash Drive, Xbox controller adapter. The devices that don't work are my 2 webcams and my Playstation game controller adapters. My older webcam used to work on this mobo's USB ports but has since ceased to function. Device manager says all USB ports are fine. I have also tried a PCI card with USB ports and my webcams/controller adapters didn't work on that either. Can anyone suggest how to get these devices to work again? Thx all for reading this.
