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.

Which operating system are you guys using? Or are you using controllers?

Raspberry Pi here, as well as a regular desktop. Gonna try the regular desktop again and see how many I can get running this time.

Okay, it doesn't sound like your 49 port hub is the problem. It's probably getting plenty of power and current.
If you are using Windows 7 32 bit, or maybe 64 bit too, try turning OFF FIFO buffers completely. This will allow the comm lines to flow wide open and freely. Set your port speed to 115,200 also if it isn't already set there.
This may help if not correct your problem. It will certainly help increase speed to it's maximum just like it has with mine.
My pods have been mining for over 80 hours since I killed the buffers! No more unexpected crashes or disconnects etc. GONE! Wink

Peace!
