Does sonoff P dongle need to be updated for Z2M

I just got my dongle and have not been able to update it, trying to set up Z2M, so two questions, does the dongle need a firmware update to work and is the dongle NOT supposed to be plugged into a usb3 port?

i didn’t update the dongle e and it worked but then had heaps of issues

I am goign to use the dongle p but not sure if needs to be updatd. i have to repair everything tho

Does not need, but highly advised

It is, bad interference between USB3 and Zigbee/Wifi. Use an USB2 port and an extension cable.
