I have HA OS running on a Rpi 4 8gb on an SD card and all went fine. I have only 1 zigbee device connected (Sonoff MIni).
When i try to migrate to an SSD its when problems begin.
With both (CC2531 and SSD) connected to any USB 2.0 OR 3.0 or veiceversa i cant connect to the zigbee devices.
I’t seems a problem of signal interference between usb’s.
Even I try a usb extensor for the CC2531, with no luck.
I go back, remove the SSD and put the SD back, and all went fine.
So i think the only solution to use a SSD on my Rpi4 it’s to buy another USB zigbee coordinator, not the CC2531.
Anyone have the same issue?
Anyone is using an SSD with a coordinator, both connected to usb? Wich device (coordinator) do you have? Im seeing the SONOFF usb donggle, but dont know if it will work with SSD.
You should put your zigbee stick on a usb extension cable and keep it as far away as possible. It is an interference problem, but this usually solves it.
I wouldn’t use the cc2531 in any event. See here for recommended devices. Supported Adapters | Zigbee2MQTT . If you want to completely electrically separate it from the pi, get an ethernet based one.
Interference has been mentioned in many threads, I’m sure you will find more info.
You should also shield both the SSD drive as well as the Rasberry Pi (by using metal enclosures), and be sure to connect Zigbee Coordinator in a USB 2.0 port (not USB 3.0) via a long USB extension cable.
Understand and remember that Zigbee signals are weak and are very sensitive to RMF/EMI/RMI interference so the technology relies on a strong Zigbee network mesh (meaning many Zigbee Router devices) and it makes it much easier to troubleshoot and find real problems if have already optimized your setup and environment to work around that.

I had a similar problem when I first tried to migrate to a SSD.
For other reasons, I got a Sonoff ZigBee controller stick (thank you, radio migration!) and just last night tried again with the exact same SSD and everything works perfectly fine.
