Got mine today. Plugged it into my machine which is currently running 2 Ant U2's with CGminer 4.4.2. I used Zadig to install the WinUSB driver for the device.
Do I need to update CGMiner or change my command line to get this to work?

UPDATE: Tried CGMiner 4.7.1 and no improvement.

Icarus detect (1:11) fialed to initialise (incorrect device?)

Is no one using else using their U3 yet?

I got mine yesterday, tried to build the CGMiner that Bitmain provides (https://github.com/bitmaintech/cgminer), but kept getting compilation errors on my Mac. Got it to compile on a Ubuntu 14.04 box but it couldn't find the device. I also tried various BFGMiner versions on my Mac and my Ubuntu boxes and the Mac couldn't find the device. The Ubuntu box found 2 of the 4 chips and is currently hashing at ~4gh/s.

I'm kinda at a loss.

So... first note, there is NO PCI-E 6 Pin on these units.

Any chance you can give us a look inside - cover off, then fan removed ?
Thanks

Sure, Ill pop one open tomorrow.

WTF Bitmain no pci-e! This is the real reason they wouldn't offer a no power brick version.

In another thread (I forget which) a link to a 30x14 cm (half a square foot) heat sink from Shenzhen was posted http://www.ebay.co.uk/itm/300-140-20mm-Aluminum-HeatSink-for-LED-Power-IC-Transistor-Module-PBC-/321199970078?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4ac902971e

By buying parts for a miner separately and putting them together oneself, one can avoid paying VAT. All that is missing is an economical board from Bitmain. If Bitmain wants to democratise mining they have to make a product that stands some chance of recouping its cost. It is most unlikely that the U3 is that.

If Bitmain really wants to support the home miner, the design has to be drastically simplified so that people can make a working miner with parts from their junk box.

Post what the MSRP needs to be for each unit.
Post what TH/s the units needs to be.
Post what the power consumption per unit needs to be.

What you are proposing is really an impossible unit at this point in time given the BTC drop. There is nothing right now that can be built to make a return and if it is only useful as a miner. Dead is home mining and possibly massive farm are dead as well especially those that do not have the cheapest hydro possible.

The threshold for UK 20% VAT is £15 (For duty it is £135) ie USD 23.96 http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp.portal?_nfpb=true&_pageLabel=pageTravel_ShowContent&id=HMCE_CL_000014&propertyType=document#P20_1804
Postage is not counted for ordinary mail.

https://bitmaintech.com/files/download/BM1382_Datasheet_v3.0.pdf gives 14.18 GH/s at 0.528 W/GH (Core voltage 0.72V, current 10.4A, Power 7.49W).

So the question is how many of these could be put on a board with a microprocessor, hopefully a switch mode power supply and a USB interface for $23.96.

Note that I've used the value 0.72 V whereas elsewhere in the spec the minimum recommended core voltage is 0.75

The situation in Europe seems to vary country by country. In France there is no threshold it seems, whereas some countries have a threshold of €22. Germany has a threshold for VAT of €22 but if the total VAT is less than €5, it is waived so the value could be up to €42 USD 52.41 (slightly more actually as Germany's VAT is 19%)

(The information for Europe I obtained from http://www.dutycalculator.com/ - but after 3 searches they ask for money and though I flushed my cookies it did not seem to help).

How can you profit from these while other miners are running on Ths?

There are still other coins next to BTC where you will be able to get some coins even with that hashrate. Even if it's only to generate "play money" to trade with.

Anyone else planning on grabbing 1 of these or a couple?

There are a few group buys, as well as resellers: https://bitcointalk.org/index.php?board=137.0

Just opened a group buy for my area actually and I am talking to some co-workers. Althought it seems just using a re-seller is going to be the best way.
