Re: TECHNOBIT support tread + customer feedback- 800 Ghs enclosed miner -269 EUR

It doesn't specify on them what chips the hubs use. One is of the Pi Hut's own brand, the other branded Cerulian from Maplin, both are 7 port with 2 amp supplies (though I have both powered by the ATX PSUs that power the miners). The way it behaved seemed to be down to lack of power on the USB bus rather than incompatible hardware as when I added the second powered hub, everything worked. As I am typing this I have 3 HEX16Es, a HEX8A1 and a Gridseed Dualminer all connected to the same Pi, all running stably using cgminer.

Yes, most of manufacture never include that information. I always ask them before buying
It's better to use same power supply with the miner.
