When using a USB 2.0 2.4GHz wireless peripheral device (such as a mouse, keyboard, or headphones) with a PC that also has a USB 3.0 peripheral device plugged in, you may experience erratic operation caused by interference. This is especially likely to happen when using USB 3.0 remote hard drives or flash drives. This interference may result in: Delayed response to mouse or keyboard inputs Missing keyboard characters or mouse commands Decreased operating distance between the USB 2.
Make sure your USB 2.0 wireless receiver is in the USB 2.
Use a USB extended cable to position your wireless receiver as far away from your USB 3.
