Just upgraded my M.2 single Edge TPU to M.2 Dual Edge TPU. No even need for driver re-installation. It works right out of the ESD carrierOther hardware is Asrock DeskMini A300 with Ryzen 3 3200, 32Gb RAM. Real powerhouse!
Where you able to get both TPU's working Code Project. The dual code won't use both of my TPUs. I even moved code project to my Linux server in docker and still the same result. So for now, I'm still using a single TPU even though the OS sees both TPUs.
