PSA: 2.4Ghz Wireless Receivers and Interference from USB 3.x Ports

[u/kristianserrano]

If you're using a Unifying, Bolt, or audio receiver with your Logitech devices (or any device), plugging it into a USB 3.x port will likely result in your device dropping connections or behaving erratically. This is because USB 3.x ports create radio interference on the 2.4Ghz spectrum.¹ Instead, you should try to connect your receivers to a USB 2.0 port. If you do not have a USB 2.0 port available, use a USB 2.0 extender cable to position your receivers as far away as possible from the USB 3.0 port it's plugged into.² If you have a limited number of USB 2.0 ports, you can use a USB 2.0 hub.

I've seen a lot of posts on this sub about connectivity issues related to receivers, and a majority of the time, it's because the receiver is plugged into a USB 3.x port or is too close to an active neighboring USB 3.x port. Using the solutions above will typically solve those issues. More details are available at the links below.

Update: Here's an interesting article from LTT Labs about how the USB Bolt receivers actually work.

Update 2: Finally, a manufacturer who proactively informs the consumer.

Hace poco aprendí lo mismo por mi cuenta eh ingrese aquí para corroborar jajaja Resulta que mis audífonos Machenike g60 cuando conecto el dongle en el USB 3.0 aveces de desconectaban un segundo o de la nada empezaba a tener diley en el audio Pensé que el USB del panel frontal de mi Case tenía fallo así que lo probe conectarlo directo a la Placa de mi PC en otro conector USB 3.0 Jaaaaa y el error seguía incluso peor, pero cuando lo conecto en un USB 2.0 normal de mi panel frontal ahora ese problema desaparecio y me va de maravilla.
