Wireless mouse and keyboard stop responding when a USB HDD or Flash Drive is connected
Many users have reported that they experienced the same problem with their wireless peripherals. The main cause of this problem with wireless devices is the interference issue with the USB 3.0 and 2.0 ports, which occurs when both the ports are located on the same side of the laptop. This interference issue causes a delayed response to wireless devices such as mice, keyboards, etc.
To solve this problem, it is suggested not to connect your USB 2.0 and 3.0 devices to the ports that are located on the same side. If your laptop has USB ports on both sides, connect your wireless peripherals and Flash Drive to the USB ports located on the opposite side.
Desktop users can connect the devices to front and back USB ports.
Hope this helps.
