Raspberry Pi tip: Use 2.4 GHz Wi-Fi and avoid USB 3

[benjaoming]

Users saying to avoid connecting USB 3 devices because of Wi-Fi interference:

if you're not actually using it, there won't be any interference generated, so, er, don't.

This is not a Raspberry Pi problem, it's an universal problem in high-current interfaces if low quality devices are connected. It happens in usb 3.0, usb c, thunderbolt in a $2700 MacBook Pro, any plug at home with a mixer or a kitchen robot working....
The solution is not stop using USB 3.0, but using normal or high quality devices on it.

Yup, agreed, I know that it's not a Raspberry Pi problem, have pointed that out in another response. The idea was to add the tip in the Raspberry Pi because the interference was raised as an issue by a Raspberry Pi user -- and because we have another issue for adding a Raspberry Pi tip :)
