+1 for D-Links and Belkins. I recommend them without hesitation.
Well that answers one question... if you actually worked for comcast you wouldn't like either of those manufacturers.

The manufacturers fucked up bad. They should have made the connection ethernet or firewire Most Ethernet chips can support upto 64 simultaneous connections, USB can only handle ONE connection at a time, no matter how many devices are connected. (you could even STREAM the requirements out of the ethernet/firewire controller into the slaves using a single connection) So once you start slapping on those GH/s units, the USB chain is going to be spending more time in negotiation/connection/disconnection that it is just not funny.
The only real solution is to DUMP the hubs and load the computer up with USB cards, then at-least you can aim for 1:1 rather than some fucked up binary tree dangling off a single USB host.

guys, it's only 4 amps = 8 ports at full 500mA USB2 specs. The details show: - Up to 500 mA power, all ports
- Input: 100 - 240 V, 50/60 Hz; 1.6A, maximum
So I think it will be fine. No it won't. Re-read the specs. Power adapter part.

Whether or not it can support full USB specs or not, 500mAmps per port is still only 4 amps for the entire hub. I doubt 4 amps is enough to support 8 asic miners working full tilt, even if the power adapter was capable of putting out more than 1.6 amps.

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."
- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'

Related to quality and durability, by my own experience, US Robotics and Kensington seems to manufacture quality.. I've had those brand for different peripheral/components, those have never failed.. except for a USRobotic router that had cofee in, it just lose the capacity to save config.. I gave it to a friend who do not matter about config, still running, 10 years old !
I really appreciate all your inputs, lots of interesting info/links in this thread ! Thanks to all !
was my 2 satoshi !

+1 (I have often thought about this) so I wonder how that 49 port psu powered hub/board slows down 49 333's communicating? thats a lot of info squeezed into the smaller pipe.

Why are people still farting around with USB ASICs? Am I missing something here?
