I don't trust these hubs at all. I've fried a few USB Block Erupters on them. They only run 3 erupters with the power supply it comes with. You can buy these for like $8 on eBay. I switched to the Rosewill 10-port hub ($25 a hub). They work great. I have 45 miners running on 5 hubs without a problem.

Like these?

That would be them. I bought them from Newegg's eBay store.

Cool

Btw, has anyone tried the Manhattan?

I wonder how many usb asics it could handle with a bigger power supply.

Got the manhattan to hold 6 anything more shuts down the whole hub, not sure about messing with the electronics to make it more powerful.

I'm sure some of you are already aware of this but Nemo1024 has done an amazing job compiling valuable data about hubs here and are discussed extensively.

That hub would be lucky to run 4 block eruptors. It has a 2A 5V power supply, all usb asics are 2.5W, or 500mA which is USB spec.

Yep! I have a few of these hubs but only use them as daisy-chained hosts for the hubs with the BEs. The wall wart that comes with it is cheaply made; I wouldn't load them to the theoretical max of 4 BEs (4 x 0.5A = 2A). Any power supply shouldn't be loaded to the max anyway. They become less efficient and produces more heat (a direct result of wasted energy). I make it a point to load them between 50% and 65% which is close enough to peak efficiency (50%); up to 75% tops if I'm in a bind and find the need to push them.

I have a wide selection. I consider the $14.99 entry level or on a budget.

It just needs a beefier power supply. Once I get mine in I will find a supplier with 5v4a or 5v5a to handle 10 usb asics and then make a combo.

Some people already have, or know where to get, bigger power supplies for cheap.

It's looks like the same generic made-in-China-special 10-port USB 2.0 hub that's all over the Bay and the Zon (comes in a variety of colors) that can be had for cheap. What makes your offering special to command a price that is more than twice the prevailing interweb market price that also offers free shipping? I'm just curious. Thank you in advance.

My supplier just started carrying these, I have tried them with usb asics and with the stock power supply they will run 3-4 reliably. I'm running one right now with 4 usb asics and it hasn't had a hiccup since I hooked it up. These hubs can be upgraded by using a power supply that provides more amperage.

A 4-5a power supply is enough to run 8-10 usb asics. Thank you mijanur for this post on how to mod the $14.99 hub for better reliability with higher amperage.

I offer free 2 day shipping and escrow is enabled.

I have a very good selection of industrial usb hubs. If you want a better quality hub please check out my listings on bitmit.
