BFGMiner Support?

That would be a huge plus Smiley

BFGMiner also in progress... Smiley

At 0.85 watt per g/hash and 5 gh/s advertised, thats a power draw of 4.25 watts per stick.  A USB port outputs at 5 volts, so simple math from there (Amps = Watts / Volts) and you get 0.85 amps of current being drawn from each miner.

Only USB 3.0 slots can support that current (and just barely). USB 2.0 ports can only provide .5 Amps of current...nowhere near enough. So does anybody know where you can get cheap USB 3.0 hubs that have an external power adaptor? Anker hubs are too expensive. I might as well go buy a non-usb based miner if I have to spend $50 per hub.

Not sure USB 2.0 cant provide more current then specs say. What if we connect powered USB hub to ATX (5V) power supply with enough Amps. Maybe the circuit will get bit hotter but it may handle 4.25 Watts. I'll give it a try with my DUB-H7 when I get a chance Wink

I dont believe USB 2.0 slots can't provide more than .5 amps beyond minor fluctuations. Its the same problem asicminer ran into with the block erupters. They draw the maximum of .5 amps from a usb 2.0 port and these will be drawing close to the maximum provided by a usb 3.0 hub (Max is 0.9 amp). Any hub that powers these will need a beefy power adaptor or it will have to be modified to be powered from the PSU.

The newer Anker Hubs come with a 5 amp power adapter and 0.9A is provided by the port you plug it into. Thats a max of 6-7 of these running on a $50 anker hub...and you are unlikely to find a usb hub that comes with an adaptor capable of providing more than 5 amps. I use the Anker as an example because its the only one I know of that has a 5 amp power adapter.

Regarding power, several motherboards and USB 2.0 hubs have charge ports with >=2 A current. Looking forward to the release of these sticks. Good job!

waiting very patiently .  I have four 7 port hubs from here



http://www.amazon.com/gp/product/B00BZABE72/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1


  they come with 5 volt 4 amp bricks,

but  I purchased 4 of these


http://www.mcmelectronics.com/product/82-12675    when wired correctly they have a blue led  wired backwards a red led. the wire fits the usb hub.


 and i purchased this psu


http://www.ebay.com/itm/Mean-Well-RS-150-5-Switching-Power-Supply-AC-DC-Single-OUT-5V-26A-130W-7-Pin-/231075735788?pt=PCA_UPS&hash=item35cd2fe8ec   

   So I can run 22-28 of these sticks.


I am running AM sticks with zero issues for now.  nice setup  lots of pretty blue leds.

Charge ports don't provide a data connection usually. They are for just that...charging. So you can plug things into the slots but the OS will not see them. The anker hubs have a port like that.

 that is why the hubs I picked are better  they will allow up to 1.2 amps per port and all ports are data ports. They have far spacing  so fitting 6 sticks and a fan should be a breeze.


If my psu can do its  power rating  I would have a nice compact 100gh plus  mine using under 130 watts.

These sticks still make money at 3 bill difficulty.  100gh of them pulling 150 watts (whole system) at 17 cents a k watt and a diff of 3 billion earn 2.50 usd a day after power costs.

This is the closest hub I have seen to what I would be looking for. But you will be lucky to get 6 of these running on that hub. More likely 5 + fan is all you will be able to do. 6 of these draw more than 5 amps of current. More than those hubs can provide.

And at $30 a hub? I might as well pay a little bit of extra money, buy the anker hub or similar knock off, and get an extra stick or two running on one hub.

 I disagree I think they will run 6 no problem, but we won't know till the sticks come.  THAT IS  with the psu attached not the brick that comes with it.

Very very interested this. What payment methods will be available? I have a 200 watt 30A PSU waiting to power my hubs for these. How about a little hint about pricing? Cheesy I have some saving to do in the short amount of time til they are ready to ship.

I don't know if you guys are aware but ASICMiner is now providing a 49 port usb hub powered by an atx psu. It comes free with a purchase of 50 AM sticks. They are shipping this week. Since its already designed to handle a direct PSU connection I imagine providing enough current for these miners wouldn't be difficult.

This is a great innovation and huge jump from the typical 333Mh/s to 5Gh/s usb miner. Maybe soon it could be 50Gh/s or more in a tiny usb stick.  Cheesy

Since its already designed to handle a direct PSU connection I imagine providing enough current for these miners wouldn't be difficult.
They require an ATX power supply with 25 amps MINIMUM at 5 volts.  That gives 1/2 amp per port with the power supply running flat out.  There are a few supplies that offer 30 amps at 5v which are a better match for a full load of erupters.  49 * .85 is just over 41 amps which would want a 50 amp supply and 10 amps per pin that I think are rated at 8 or 9.

So, while the ASICMiner hub is a good match for 1/2 amp sticks when paired with a 30 amp supply, I don't think it would be a good match for higher power devices without some creative rewiring.

I have this 20 port

http://www.ebay.com/itm/20-USB-ASIC-miner-Block-Erupter-20-Port-Hub-for-Bitcoin-Mining-/111198908832?pt=US_USB_Cables_Hubs_Adapters&hash=item19e3f8b1a0  

 with this psu

http://www.ebay.com/itm/NEW-GENUINE-LENOVO-THINKPAD-135W-AC-ADAPTER-FOR-MINI-DOCK-PLUS-SERIES-3-/130881117762?pt=Laptop_Adapters_Chargers&hash=item1e791f5e42



the hub came with this psu


http://www.ebay.com/itm/10-Lenovo-90-Watt-20V-4-5A-AC-Adapters-FRU-P-Ns-42T4427-42T4431-42T4-Genuine-/231053953156?pt=Laptop_Adapters_Chargers&hash=item35cbe38884  


  so 20 hubs accessing a 135 watt psu    may work okay.  


works great with 20 am sticks.


figure 80%  x 80% = 64 %  of 135  or   a true 86.4 watts at 5 volts   divide by 20 =  4.32 watts a port  that is about  .864 amps per port.

the first 80% is conversion of 20 volt to 5 volt.  the second 80% is  the safe rate for 24/7/365 ops.

 so that hub with the better  power brick may be safer.

20 x 5gh sticks would be a very nice piece of gear.  I can't wait until NOV 1 to order some.

Summing up the discussion on power spec.
One of our mining test that summary you can see in gallery, was running on laptop with USB 3.0 port.
So we know that 5+GH/s from device can be easily acquire with normal USB 3.0 spec.

To meet customer expectations we will provide sufficient USB 3.0 hubs in our store, that's every one can buy hub and get it in one package with ordered Bi•Fury's, to minimize unnecessary cost.
Now we are in negotiations with some producers to provide hubs in good price on right time.

First we thinking about Dipol Hub's.
But price per port is still very high.


For now we are most believe in ORICO A3H10 hub.
Price per port is right and quality is very good.

Hubs come with 12V4A external power supply, and manufacturer assured us that every port meets the full specification USB 3.0 (5V 900mA).



I will update some info about hubs and Bi•Fury sale in next weekend.
