There seems to be a major slowdown in NYC with customs.  I have had a RedFury trapped there for over 1 week with no further info.
They are slow.


mine is stuck in customs in New York.  Maybe I will get it on fri. I am looking forward to using it.

If I buy this hub, then I need to buy the USB cards and run it using my computer? Does it matter what computer I have or what USB port it needs?

I can do my best to answer but may get corrected later  Grin

What comes in the box is the USB hub (metal inclosure), a power cable (for connecting to a socket), a USB cable (for connecting to a computer), and a USB LED fan (pleasant surprise!).

You have to buy the ASICs and whatnot separately, this is only a powered hub. I honestly haven't checked power usage or anything but so far the ASICs are running great off a Raspberry Pi. Takes far less space and less hassle than the D-link hubs I was using.


Yep, I was going to do FREE fans with all the hubs (as a thank-you to purchasers )BUT then I found a CRITICAL Quality assurance problem with the fans, and am now sitting with a SHITLOAD of useless fans

Please don't use swan neck FANS with hub/ computer.

1. The fans have a contact that is copper and fails after about 1 week of continuous running…….. fan continues but lights die (not critical, just an annoyance)
2. The fans vibrate and transfer the force down the swan neck and into the USB hub socket… thereby fucking them up………. (critical failure, can damage USB connections)

Please don't use the swan neck fan  directly into ANY fixed USB socket, this is why I think it is difficult to find swan neck fans, and yes I know 'loads of people use them', but I am fairly scientific in most things I do.



Additional taxes…on delivery.. Hong Kong is a free port, and I'm currently looking at ways to pass that saving on……, but ultimately it is down to YOUR local government and customs.
Air post is fairly stringent on declarations, what with people trying to blow planes up…..
SPEED POST demands 3 copies of an invoice is supplied with the documentation.

regarding Power usage, the unit contains a switched mode PSU, so it should be as least as efficient as a phone charger…


A bit of background
On Testing…
Normally I'm fairly private, but I can say I have over 30 years experience in Quality assurance & design/electronics, 25 of which are in China/Asia.
(which is why my first post was a bit technical)

At my last company I managed 3,000 products out of a 28,000-32,000 range and dealt with/controlled about 110 factories over a period of 16 years.
If you live in The UK or Europe, you may see some of the products I have designed. (Homebase/Argos)

The issue is not finding product in China or using a translator for TaoBao/ ali…etc, but rather ensuring what you purchase meets the required levels.



I evaluate Circuit layout
to make sure I get what was agreed…



Here I use  a PAT (portable appliance tester), this  performs leakage, flash test earth bond, cross wired & short tests, This is in addition to the factory tests….
Nope!! I do not trust Chinese factories to say they will do what they agree too.

On 'UK 3 pin' Cables….

Yes I know…. they are NFG (no fucking good) other than for a few countries in the world.
For this shipment I figured people would just substitute in the 'correct' cable, Yep… even I get caught out by the idiots sometimes….
Normally I do on-site inspections BEFORE taking goods, unfortunately before Chinese new year is a problem.

Purchasing 8 please! ~$112.8 per unit, plus shipping. Very much looking forward to receiving them.

UPDATE
One unit received and loaded up:


16 Yellowjackets... mmm...


All overclocked to 54 oscillator bits, there don't seem to be any power-related error messages; it seems rock solid

Very happy, can't wait to get the rest!

I'm interested but sort of iffy on how to calculate what to send.

Don't suppose you could post an official price of the day, or something.

If not, what would I need to do to qualify to use paypal?
My ebay account is in good standing, if that can put your mind at ease Smiley

we use the coinbase.com btc valuation to determine btc price. Just check it out at the time of sending then minus 6%
I have sent a PM with details about paypal payment as well.

Nwoolls, thanks for answering those questions, its sounds correct to me. The casing of the hub is made out of steel. They are proper mens hubs as my grandfather would say  Cheesy

The hubs themselves run cold but i have heard some people post before about cooling the miners which can get quite hot. I think everyone's setup is different but i have five hubs running at the moment with 16 red furies in each one. I haven't used any fans and they have been fine for the past 3 weeks. Although it is the middle of winter at the moment so temperature is a bit cooler than usual.


How many logical hubs is it?

(For example, a typical 7-port hub is two logical four-port hubs, with hub #2 "plugged" into a port of hub #1, leaving seven open ports for the user.)

Reason I'm asking is, the Raspberry Pi can have issues with this hub if there are too many logical hubs inside it.

I think they are three logical seven-port hubs. So each hub used counts as 21 usb ports with 19 usuable. Razorfish correct me if i am wrong here!

That sounds like a good plan.
I would put my BiFury and Red Furies in it with some of the old block erupters. 
Hopefully I can get one soon too.  Grin

Newbie question incoming...

If I buy this hub, then I need to buy the USB cards and run it using my computer? Does it matter what computer I have or what USB port it needs?

okay windows 7 and a pc with a usb 2.0 port should be good. ant miner usb u-1 sticks or ice furies or red furies should work well in the pc.

this hub is a stud/ a high end hub.  At least in theory it is.  So far users like it.

 I plan to put about 16 ice 'nano' furies in it. an attach 2 fans to it.  the guy above uses a raspberry pi I never tried it.  I run  4 pc's with windows 7 because I also run the gpu's in them at lite coin.

 the  4 pc's are dedicated for mining.  i use the macs I have for the net home theater etc.

That is great to know.
Is it metal or a plastic case? It looks fairly rugged.

Thanks for the info. Does it work well so far?

Got mine today (US) - works great!

Received my shipment today. Came with a UK cable and had to pay import duty, otherwise all good, thanks!

Okay where are you located USA ,UK?  If USA what was the duty?

Northern Europe. It was about 35USD equivalent.

Very true.  With shipping it puts it just out of my range.
But it looks like it has great spacing and lots of power for all devices.
As it is now mine are spread on among two Anker 7 port hubs.  They work great but spacing is an issue with the BiFuries and RedFuries.


I'm looking forward to seeing how well this works for you.
I really want to get one as well when I get the money for it.
I do hope the price comes down a bit though.


yeah these would be nice at 150 usd vs 200 usd


Well it is getting closer to my home. In New Jersey:

I will use 14 ice fury  sticks and see if I can get a high over clock.

Right now I get a 54 setting on my ice fury sticks.

 This means about 2.5 a stick.. If I get a 56 or 58 setting to work the sticks may push the 2.8 level.  I will post photos.
