I have a D-Link DUB-H7 for 4 or 5 years now I think. I have never had any problems with it. The only problem is that it does not contain any USB 3.0 ports.
+1 for D-Links and Belkins. I recommend them without hesitation.

Question:
Imagine you can have a heavy duty 5A 10-port USB hub. Imagine such product exists. Would you buy it? How much would you spend for it?

Nevermind. I think I already found a viable commercial product, without the need for me to go through the hassle of building one. http://www.amazon.com/Plugable-Port-Speed-Power-Adapter/dp/B003Z4G3I6

so does anyone know if there's an upper limit to the current a hub can support? I ask because I'm curious what would stop me from buying a 10 port hub with an external power connection and providing my own 5v 10a power which should be ~ 1a per port
it's doable and would not be hard at all, but I was wondering if anyone had experience putting more than a few amps through a USB hub.

Putting more amps into something then they were designed to handle usually will fry them. I've never tried this with USB hubs, but I have experience frying amps in my car lol.

good point, I also forgot that it's usb 3.0 that has ~900mA per port not 2.0

Its cool,but thats not a powered hub,it won't work for the Jalapeno's,only for the SC Singles 30 or 60 gh models. It is a powered hub - says right in the description. You need to put a 5v power supply into it, and I don't think one is included. I'm doing SCs and bASICs, so it won't matter. Ah,I just looked at the pic & saw no wallwort.So you need to buy it seperately They say 1 amp,so you can run only 1 Jalapeno.Oh well.............. Hmm I wonder if you have a PSU molex 5v and ground if you could just wire it directly into the DC barrel on there. It would definitely supply more than enough power for some jalepenos. I believe that would work.

That looks like the Rosewill rebranded (or vice versa)

If a powered USB hub is not necessary, is it of any advantage (in terms of reliability, etc). I n other words, assuming, as has been widely reported, that ASICs are powered via barrel connectors, would it be any advantage, still to connect them through powered USB hubs, or would this be needlessly redundant?

For a Single or other device that gets its power elsewhere (and presumably doesn't need any significant power going over USB), there should be no need or advantage to buying a powered hub. However, it would definitely be an absolute necessity for Jalapenos.

an unpowered hub would not run 1 Jalapeno in almost all cases. The voltage loss, limitations, and the fact that most single USB ports can't get to 4.5W, it's not going to work for most people.

The only need for a powered USB hub is for the Jalapeno's.All other ASIC's don't need it,a standard hub will do

because the wires inside it will melt Assuming you know what you're doing to provide power from the power supply; the main point is you can use power injectors.

I almost bought that hub when it was on sale for $25.

guys, it's only 4 amps = 8 ports at full 500mA USB2 specs.

- Input: 100 - 240 V, 50/60 Hz; 1.6A, maximum
So I think it will be fine.
