I had my first 20 grid seeds working on a 49 port hub
and on Monday i got 30 more in
now i can not put more that 25 grid seeds on the 49 port hub if i do then all the grid seeds stop mining.
i have changed the PSU with one that has a 25amp 5v rail but its still the same
now I'm looking for a different usb hub to use.
had anyone got any of the 10 port hubs that come in the grid seed accessory pac they are not using and want to sell ?
When you say "not mining", do you mean that it's hashing, but not submitting any shares? That's the same issue I'm getting, but my limit seems to be around 7-9 Gridseeds.
