I can't even get these hubs to hash without some serious HW errors unless i only have like 2 usb miners in each of the hubs connected to the main hub.... Any help on how to get 15 miners working well on 3 dlink hubs please let me know. Or do i need a 4th to spread out the power, all i know is the roswell 10 port can easly take 7 or 8 just cant use it like the dlink in that i get com errors? i dont know i dont have 2 to try..

I thought the same about the power draw.. His pi's are running off his hubs, which i have and they are giving me problems. When I connect 2 dlinks to one, and that one's connect to pi. i cant even run 10 on the 2 connected hubs that way, 1 always doesnt start and have hardware errors. And my Pi is powered with its own supply. LOST!

I refuse to run my rPi's off the hubs, just doesn't seem logical when I have tons of extra 5v 1amp USB connectors sitting around (Apple i-Device chargers), plus I recently bought a nice surge protector that was laid out spaciously (to allow for power adapters), small surprise was that it also had 2x USB 5v @ 2a connections, so now I use those.

Also worth mentioning (possibly), power conditioning, not sure if this plays a huge role in things or not, but I noticed when I switched from a cheap surge protector coming off my UPS system to a not-so-cheap surge protector which had in-line power conditioning as well and not connected to my UPS, my rate of hardware errors has drastically gone down, a lot. Found this to be interesting, since I only changed the surge protector and the outlet to where it was getting the power.

I run RHB-500 Rosewill 10-Port hubs w/8 usable... I tried the "use the red wire (5v) and ground to a barrel-plug adapter from a PSU" (to get it to run all 10 ports) however the PSU I bought for $10 (still 400watt), tired it on one hub, couldn't get more than 6 to run... and couldn't find my multi-meter so I just said screw it and went back to using the power bricks, lol. I imagine it's due to the cheap-as-hell PSU...

Yeah i have 8 on a roswell in my config like i said and no problems with that guy going to replace these dhubs with another roswell.
