Sonoff Zigbee 3.0 situation

I ordered some Sonoff Zigbee 3.0 USB Dongle Plus-E sticks from Amazon, the first one was great. Was able to connect to it, flash it up to ember… all well and good.

Order another one, and while it looks the same, it is behaving quite different.
It reports…
ID_MODEL: Sonoff_Zigbee_3.0_USB_Dongle_Plus
… rather than…
ID_MODEL: Sonoff_Zigbee_3.0_USB_Dongle_Plus_V2

The board, when taken apart, says…
Zigbee 3.0
USB Dongle Plus
2021-07-09
V1.3

I can’t connect to it with putty and even if I could, I’m not sure what I should flash it with.

I can’t get it to work in HA even as it is. I get the error that it failed to start the EZSP layer with Host Fatal Error.

I’m out of my depth with this and AI hasn’t been able to help.

Grateful for advice please.

I’ve worked out that somehow I’ve got the P adaptor.

Upgrading the firmware for this is irrelevant to the ezsp/ember issue so not worth pursuing.

Using the zstack adaptor option gets it working so the option is to continue with this until it gets to the point where it breaks… and then upgrade the adaptor… or return it as not what I ordered and get a replacement.
