I suspect that we are stressing these more than the average user. I'll bet the designers never anticipated these running 24/7 drawing full current.

wow. Orico hubs are now perfect copies of the Anker hub.
It is a good hub. Behave exactly as the Anker maybe even a little bit better.
I have 1 Anker and 2 Oricos (not the same model than the one on your picture).
Maximum BEs for stability:
Anker: 8
Orico: 9
No idea why it seems I am the only one not being able to use the 10 ports

I have 10 running on the Orico with the 4 amp power supply.
Sometimes you have to shut off the hub with the push button switch and power it back on, it works perfect once you get the 10th one recognized.
The question is: for how long?
With 9, I can run the setup stable 24 h/ 7 for weeks. As soon as I add the 10th eruptor, it will work fine but it won't last more than 24 hours before I get a couples of BEs with the green light stuck....
My Orico hub powerbrick just died before the 30 day return policy expired... lucky me..buyer beware, YMMV
It seems there are many of the same model rebranded, I got a cheaper lookalike 'Aitech' running right now

Ghetto cooling duct here again.
Hard a go are re-flowing the solder on the USB hub that had about half the sockets not working and gave it a +5V power trace augmentation, but I think I may need to replace the sockets. Or wait until I have a reflow workstation (thank your element14 Father's Day specials). Also ran into problems with comms errors, decided I should measure the +5V at one of the miners, it was down to 4.90V at the miner, with 5.16V at the PSU, so I adjusted the PSU voltage up to 5.4V (5.06v at the same miner), and the comms errors stopped. Two more hubs on their way from DX.com for modification (along with some 3300uf 16V caps to repair an ATX PSU with a 45A 5V rail), though I may just get a 5V 30A supply instead, since the voltage can be adjusted up to compensate for ohmic losses.
Are you using http://dx.com/p/42838 ? Mine just came today and it's not a bad little hub. I opened it up as much as I could without breaking anything and it looks like the power plug is through hole soldered so should not require a reflow machine to replace that crappy little socket with a wire.Hard a go are re-flowing the solder on the USB hub that had about half the sockets not working and gave it a +5V power trace augmentation, but I think I may need to replace the sockets.

The power plug is the same size as a dlink dhub8 and not 5.5x2.5 like I was hoping. My raspberry pi saw it just fine so I moved 4 erupters from a dlink along with the dlink power supply to it and they are mining away happily. I am not sure I would want to try to push 5 amps through that little plug so a hardwire might be in order if I keep using it.
I also picked up http://dx.com/p/230094 on a whim and to my surprise it is NOT three x 4 port IC's but one "Terminus Technology Inc. FE 2.1 7-port Hub" cascaded to a "Terminus Technology Inc. 4-Port HUB".
The first one was the expected 3 x "Terminus Technology Inc. 4-Port HUB" configuration.
Finally, that 5v 5a supply referenced by several people earlier in this thread and listed in the OP arrived last week. It comes with a 5.5x2.5 plug plus an adapter to get it to 5.5xsomething smaller. I gotta admit, it doesn't look like a 5a supply. It is half the volume and weight of a UL rated 5v 4a supply. I don't think I am going to use it on anything and sure don't expect 5 amps out of it. Be careful out there if you running unattended equipment and stick to UL rated supplies. I am not saying that the unrated made in china supply that is half as big as it needs to be will catch fire and burn your house down but I wouldn't be surprised if it did.

I bought a Balance Form 10 port USB 2.0 Hub from Amazon (with my prime account - free 2 day shipping) for ~15$ shipped. It comes with a 3A power supply and can be found here: http://www.amazon.com/gp/product/B00BGT3JKM/ref=cm_cr_ryp_prd_ttl_sol_4
I have been running 5 units on it for 3 hours without any issues. It should be able to run 6 units (it has 3A PSU) I think but I didn't want to push it. The only thing about it is that it is horizontal orientation by default (and thin / close to surface) so you will either want to elevate it or mount it vertically.
Also, I bought the RHB-500 from newegg (while it was on sale) for about 20$. I am running 7 units with a USB fan on it and it is going great.

The 10 Port USB 3.0 Hub with a 12V 3A power adapter from Gearmo has been working exceptionally well for me using all 10 ports, especially @ $49.99 on Amazon.

I bought 4 of these and they have been stable for well over a week now. Not a single issue. The only drawback is they are USB 3.0 which probably won't work with a raspberry pi.

My 4 original hubs are still running stable for almost 1 month now and I just added 4 more last week. I really love these hubs.
you're running 10 in them? 3 amps should only support 6. is the power brick hot?USB 3.0 is 12V 3A = 36W is more than enough
my bad.

The power bricks are a little hot to the touch without a fan for cooling, but with fan (box fan) for cooling the power brick is a lot cooler. Plus the USB hub is all aluminum and that helps a lot with the heat dispensation.

I got 2 more plugable 7 port hubs. I already had one. The one i had is moody with 7 erupters. they'll run for days and then one will stop. Always the same one and uplugging it and then plugging it back in resets it. well, the first one i openned had a power supply that wouldn't come on. Bleh. the other new one seems to be running fine so far. I went with these because they are cheap, but not gonna buy any more of them. I ended up buy angle plugs so i could use all the ports and that nullified the cost benefits. I'm just going to bite the bullet and get more anker/oricho type 10/9 ports. they use the least amount of surface area on my shelf and work best with the artic fans. I'm going to use free standing fans on the plugables if the fans ever get here.
on another note, i added a 5 port PCI-e card, and a 4 port PCI card. Those are the numbers on the card's edge. one had two internal ports and the other had one. i ran the internal ports out of the case using cables. I'm running Ubuntu Linux and it seems that these cards just worked as is, no special drivers. They came with mini CDs with windows drivers. This computer was built just for mining so it doesn't have a CD player. Glad they just worked. So now i have lots of places to plug hubs in. I prefer not to daisey chain the hubs. I really can't see me using 12 more hubs, but if i do, the MB has room for 2 more PCI cards and one more PCIe card.

My ST-Lab/Rosewill is running really well. Its power adapter is also cooler to the touch than D-Link's adapters.

Update on my cheap 10 port hubs - the DC Barrel plugs melted on the two cables I made (my crap soldering is most likely to blame), so those two hubs now have had a DC Barrel jack-adectomy and now have a power cable soldered directly in place of the jacks. And some of the USB sockets need re-flowing - intermittent power connections to them.
Sounds like a fire disaster waiting to happen.
Have you tried those non-soldering barrel plugs and thicker cables?

This is an update on the MCM hubs. As I've mentioned in my initial review, it supports seven miners. There are only 46 miners on this setup; 1+2 rear ports on the last two hubs respectively are not populated (waiting for more miners to come in):
...and here they are in action:
http://s1330.photobucket.com/user/visdude/media/MVI_0112_zps64f2f52e.mp4.html
The hub stands/bases were originally affixed onto the desk (here) but I found it to be inflexible and inconvenient. So, I got a cheapo clipboard and a roll of masking tape at the local 99-cent store and made a movable platform out of it to organize the hubs. This setup is ideal with these hubs since one can just pull it from the base and work on it independently from the rest (modular). Partly seen in the lower right hand corner of the image is another hub. I have started to create another row of seven MCM-type generic hubs (all black this time) along the other side of the clipboard. I'm pairing them with 4A bricks (much better alternative than wall warts in that it does not waste and occupy two outlets on the power strip). It comes out a little cheaper than MCM's without being subjected to exorbitant shipping charges and applicable sales tax. I would also have a bit of a headroom power wise (.5A more).
The setup is currently hosted through a single USB 2.0 port on an old netbook and draws 11W off the wall while mining.

Like the price of hub. What did you pay for the usb swivels for back two ports?

A small curiosity update on the internal layout of D-Link DUB-H7. It consists of 2 4-port hubs, where the second hub is connected to the fourth port of the first one.
The 2 charging contacts are on the second, nested hub: counting goes from left to right.
