My FM2-A75MA-E35 motherboard will not recognize any USB 3.0 device. I think this is due to 4 "unknown device" entries in my device manager. I am not sure what to do to fix this. My system has been stable up until 30 minutes ago, where I tried to plug in my USB 2.0 drive, and my computer rebooted when my USB touched the USB port on my case/computer. I am not really sure what to make of these unknown devices and the random reboot. Any advice? Thanks
