I'm getting 50 (and more in the future) USB miners. What USB hub should I get? No idea what is good these days.

anker?
edit: for some reason, I thought you were trolling me with a random word. Googling shows up a bunch of usb 3.0 hubs. I heard USB miners and cgminer/bfgminer have problems with usb 3.0 though. Is there a usb 2.0 hub out there thats reliable?

Hmm,that power supply is 12 volt, but I thought USB was 5 volts? O_o Which is it?
I don't want to fry my usb miners.

does not work *directly*, but if I have a 5-port hub with 5 ankers attached, it *should* work, no? |

The Anker works fine on cgminer 3.1.1 in Windows with the COM Port Drivers. RasbPi is a no, and Linux I'm not sure. Single cable solutions are my kinda thing, so I hopefully lucked out since I just bought this 2.0 powered hub very cheap (less than $5 per port). I'm hoping it works on the RasPI with the included 400-watt PS. I may not ever fill it due to ROI, maybe when the K1's come out. http://www.engadget.com/2009/07/23/cambrionix-49-port-usb-hub-for-professionals-nerds/ |

I use Ubuntu 12.whatever LTS and the 10 port Ankar works fine with 7 USB ASICminers and a fan. It will work fine with 9 USB and a fan. Yes there is a problem with the Pi. apparently, the miners are USB 1.1 or some such, the hub is USB 3.0 and I think the Pi USB 2.0. Somewhere along the line one of them gets confused.
Regardless of what the Ankar's power brick says on it, at the USB plug it is 5.5v, it will not damage your miner. Which machine you use to host your miners will determine what you can use. If it isn't a Pi then the Ankar will work fine. That is what most people use.

For me cgminer 3.2.x and higher (running in raw USB mode) has intermittent problems with USB block eruptors on the Anker hub. A device would randomly zombie out, and suddenly reappear as a new device. Shortly thereafter cgminer would crash.
However, cgminer 3.1.x which still communicates with Icarus devices in the serial-USB mode seems to run just fine. I am guessing that it is only a matter of time before this gets sorted out.

Where did you find this so cheap? The only place I can find to buy it is asking over $1,000 usd That USB hub is badass, I want one! |

Does anyone here suspect this would be a problem powering up 9 erupters and a fan? http://www.rosewill.com/products/1543/ProductDetail_Specifications.htmI think, generally speaking, it's the power supply that comes with these hubs that determines how many erupters can be powered up simultaneously, and not so much the hub itself. |

This may be slightly off topic but...
How hard would it be to make a powered USB hub yourself? In the simplest terms all you should need to do is open up a non-powered hub and connect all the USB power contacts to a separate PSU capable of supplying the correct voltage/amperage. Then even connect a few together and make your own 49-port hub. granted it may not be a nice looking but for $1000 it might be worth it.
Just a thought.

The 80 port one above is $169. The 49 port for over $1000 is presumably priced and sold by Fried Cat. |
