i recently upgrade my OEM medion Motherboard to the Asrock z170pro4s. i always used this wireless headset: http://www.speedlink.com/?p=2&cat=4416&pid=27218&paus=1 . it worked perfectly fine with my old mobo, but with the new mobo it doesn't work anymore. the light sometimes flashes on on the little transmitter box that is connected to my pc with a usb. does anybody know how to fix this?
