Cannot Connect new Devices to conbee II Stick

[Hedda]

Now, you mentioned USB 2.0. I had my old stick plugged in the USB 2.0 Post and now my new one in the 3.1 port. Why should I use the 2.0?
Also, I ordered a USB 3.1 Extension cable, but It’s shielded to avoid interferences.
So my questions now are:

1. Is it okay to use the 3.1 port or better 2.0
2. Is it okay to use a 3.1 shielded extension cable?

I didn’t think about this, but why is it a problem?

Connecting with a USB 3.0 extension cable to a USB 3.x port can cause EMI interference, (and worse is having other USB 3.x devices close to the Zigbee radio).

It is ok to use USB 3.x cable to a USB 2.0 port, but not OK to use it with a USB 3.0 port. If only have a USB 3.x port then must use a USB 2.0 cable or a USB 2.0 hub so that the port get used as a USB 2.0 port.

That is all covered by the guide (in detail and with references). The point with with me writing that guide is so that it does not have to be explained seperatly to each person individually

Please read the guide and only ask about stuff not covered by it if possible.

Zigbee networks: how to guide for avoiding interference + optimize using Zigbee Router devices (repeaters/extenders) to get a stable mesh network with best possible range and coverage

Who is this guide for? I have tried to make this guide to be a comprehensive collection of the most basic yet essential tips with a set of actions and best practice steps that should be applicable to all types of Zigbee setups, regardless of what type of Zigbee adapter/gateway/hub/bridge/devices that you are using. This guide is meant for both those who are new to Zigbee as well as those who been using Zigbee devices for years but might not been aware of the underlying prerequisites to optimiz…
