I have still the problem that 1 Miner over powerd USB-Hub works
and if i plugin the second Miner my PSU crashes.
Is there a problem with the USB-Hub Power? If have 4 Amps powersupply on the Hub.
BTW....
I use a TL-MR3020
Thanks for help
Do not use power supply that come with your hub. You should get the power from your PSU, including the TL-MR3020.
