Hi,

i also got 2 of the sticks. And still have a lot of NewPacs. I am using an Raspi 3b+ Now my Problem.:
I can add 11 sticks to my hubs and everything works fine.
At the moment i put the 12th stick in, i get an error: failed to initialize....
Doesn't matter which frequency or which sticks i put in. So there is no Problem with the Power.
I guess it have something to do with the USB Bandwidth, Maybe anyone knows how i can fix the Problem and add more sticks?

I would be very happy if somene can help.

Peace
