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 2.0 wireless device and its receiver There are some techniques that can help early adopters of USB 3.0 to mitigate potential problems with their existing 2.4GHz wireless devices: If your PC has multiple USB 2.0 connectors available, separate your USB 3.0 and USB 2.0 receivers by as much distance as possible. For example, if your PC has a choice of USB 2.0 connectors, use the one on the opposite side of the PC from the USB 3.0 connector. Position your USB 2.0 receiver as close as possible to your wireless peripheral (mouse, keyboard, headphones, etc.). Use a standard, USB-extender cable to position your USB 2.0 wireless receiver as far away as possible from your USB 3.0 connector. NOTE: A USB 3.0 connector sometimes referred to as Super Speed USB or SS, normally has a blue plastic insert in the connector. Unlike a USB 2.0 connector which has 4 pins within the connector, a USB 3.0 connector has 9 pins.Move your USB 2.0 wireless receiver to the opposite side of your computer: Make sure your USB 2.0 wireless receiver is in the USB 2.0 connector closest to your wireless peripheral: Use a USB extended cable to position your wireless receiver as far away from your USB 3.0 peripheral as possible:
