This is actually recommended to get the sticks away from any potential sources of interference
I know Green isn’t a Pi but you should know its almost impossible to get a Zigbee coordinator stick working on a pi plugged directly into the port. (and why Skyconnect ships with a short usb extension cable. - there’s a video on YouTube showing how had interference can impact your setup…)
Reccommended - use a USB 2 port (read: not the blue or orange ports) and/or hub (yes, 2, not 3) because usb 3 runs at approximately 3Ghz and creates even more interference adjacent to the 2.4Ghz band and don’t plug a USB connect SSD into the same hub.
I personally run a tiny USB2 powered hub to also keep the extra current load off the Pi.
Finally when you get it and set it up. Instead of using the USB virtual shortname (looks something like /TTYACM0) for best practice - look through the forum on how to identify the long by-id path to the stick and use that instead. If your usb ports ever move around on you (it can using the shortname) the stick still works because you’re addressing it specifically by its port name not the port you think it’s plugged into…
Also +1 on avoid combo sticks.
