Dados os novos detalhes, parece ser um caso de interferência USB 3 na banda de 2,4 GHz.
Da nota da Intel sobre USB 3.0 Interferência de radiofreqüência em dispositivos de 2,4 GHz (links de páginas para o download completo em PDF):
The purpose of this document is to create an awareness of radio frequency interference to wireless devices operating in the 2.4 GHz ISM band as a result of certain USB 3.0 devices and cables. [...] The 2.4 GHz ISM band is a widely used unlicensed radio frequency band for devices such as wireless routers, as well as wireless PC peripherals such as a mouse or keyboard.
Entre as recomendações para atenuar o problema, postadas em um wiki da Logitech em Potencial interferência USB 3.0 :
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-adapter cable to position your USB 2.0 wireless receiver as far away as possible from your USB 3.0 connector.
O último pode ser o melhor para tentar no caso de uma estação de encaixe, onde o espaço entre os conectores USB é geralmente apertado.
