When you are having to restart is it just restarting the cgminer?  Or do you physically have to power the U3's?

I'm hoping the first if so I might be able to write a batch file for it.  If have to physically power the U3's the batch file would do no good.

The fact that they are not stable and zombie for no apparent reason.  Look back at the last 3 to 5 pages, I have written on almost every one.  Sometimes a unit will run for a week without issues and then that same unit will need to be restarted numerous times in the same day as it rolls through USB ports.  These devices are pure crap!  I've tried the version of CG Miner that is available on Bitmain's page as well as 4.9.0 and 4.9.2; all versions aren't stable once you have multiple U3's on the same computer.  Even now, I have all 3 running on separate computers and still had to restart one this morning and another at lunch time.

What part is not working?   If you give more info we might be able to help.

You don't really give any info to what problem is.

Can you send it to me?

This is funny, I have 3 that I'm hellbent on getting to work correctly...  So far, no dice!  

Well I still have 2 of them, if anyone is looking to buy 1 I'd part with it.  I'll keep 1 just to torture myself with.

They're not as good a deal at the price point, but I'll second Mikestang. I got two of them a few days and they've been hashing away happily.

Yes, it's the gekkoscience compac, get them while they're hot: https://bitcointalksearch.org/topic/run-2-closedsidehack-stickgekkoscience-compac-official-sales-thread-1126705

Best usb miner available right now, and you're supporting our "local" community.  Unlike the U3, these work!

I am using 10 Antminer U3's in Tandem, with a MAC, using cgminer for mac, got my Antminer U3 from..http://www.markettwister.com/products/antminer-u3-65gh-s-asic-bitcoin-miner

and got my cgminer from a site by googling keywords, mac and cgminer.

Currently it rolls out around USD 4/ day...it came with a power supply which is 1W and I just needed to plugin a power cable into the supply.

The average hash is around 54/G/hs per Antminer....I love it..

Note:

1)   Power consumption: Quoted figures depend on your PSUs efficiency, the ambient temperature and the accuracy of the power meter.
2)   PSU: You must provide your own ATX PSU with 1 PCI-e connector, or a power line.



Features:

Scalable: Multiple U3 miners can be maintained by one controller running cgminer due to its USB port.

Hassle free: Setup consists of plugging in the USB and power cables and running Antminer CGMiner.

Cool: U3s remain cool and quiet due to its 80mm fan which quietly exhausts air out the side of the case.  

Stable and Accurate: Based on the tried and tested BM1382 chip, the U3 is extremely stable and is able to run 24 hours a day without problems.

Exquisite: The refined design of the U3 allow it to blend on any desk or shelf without standing out.

I had one for a couple days and ordered 2 more, I should have waited (and you should have, too). 

Soon the zombies will come.

Read this thread from the beginning, I pick up in there somewhere around the middle I think.  It always starts out roses.

What problems do you have with it?
