I have 3 Juiced Systems 10 port USB 3.0 hubs each running 9 block eruptors plus a USB fan. I haven't bothered testing them with 10 miners because I am using the 10th port for a fan. They have been mining for about 2 days now with no problem. I actually like their greater density compared to the Anker 10 port. It makes one USB fan cool them much better. Since I don't know how to include an image in my post, I posted an image here:

I bought the Juiced 10-port from Amazon and suggest getting something else. It'll run 8 erupters but when you plug in a 9th it starts to lose contact with one, then another, then another and the only way to fix that is either restart cgminer or unplug/replug the miner. The Anker's extra amp makes a big difference.
Adding insult to injury my Raspberry Pi can't see this hub at all, so I think I'm going to order the Anker from Amazon and return this one.
Are you sure that it isn't a problem with your USB driver or something like that? What OS are you using? I am running bfgminer on Linux Mint 15 with no problems with 9 Block Eruptors on each hub.
