I got a brand new U3 straight from Bitmain over amazon. Have been fiddling with it all night and can't seem to get it recognized by CGminer. I have done all the steps and don't know what else to do? Any ideas would be helpful.
My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)
I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.
My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"
When I start CGMiner it says "No Devices Detected"
What am I missing? It seems to be recognized by my computer, but just not by CGMiner.
Maybe start CGminer THEN plug the USB in  That's how CGminer worked for the little gridseeds,at least for me  |

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

I have tried it on my main desktop through USB 3.0 and 2.0, then on my little netbook that I used to run all of the AsicMiner USB devices, which should be 2.0. I am not using it through a hub, I can try that too as well though. |

Powered hub can help with dropout issues as there is a reasonable amount of 5V load. |

I've had great success running one of these units. I have it on a powered USB 2.0 hub and use a molex 4-pin to barrel plug of the 850w psu my S1 uses. Using cgminer 4.90, 775v 237.50mhz gives me a super stable ~57.5gh.
Did you ever try getting more than one running at the same time? I bought two more U3s, but I can't get more than one of them to run at the same time; any of the 3 run fine by themself. Using stock volt/freq for all of this, I've tried launching cgminer with 2 plugged in at the same time and I get constant LIBUSB from both devices. If I unplug one the other runs just fine. If I launch cgminer with just one running it hums along perfectly, then I'll hotplug the second one in and instantly the LIBUSB errors start. I've tried with them both plugged into my powered USB 2.0 hub, and tried with one in the hub and the other in a separate USB port on my computer, but no matter what if more than 1 is plugged in I get LIBUSB errors. Any ideas?

Check you powered usb hub chip. Is it STT or MTT chips? You need usb hub with MTT chip. |

You need usb hub with MTT chip.
How would I go about doing that please? It's an Ensignia brand from BestBuy, model number NS-PCH5421, 4-port USB 2.0 hub. 5vD.C. ~100mA, thank you. |

Some how it's hard to know unless you open the hub & check the chips type. Or you can mail the manufacturer about the chip. And do not used the original dc supply. Get the power from your PSU. |

I will research, thanks. Yes, I have them running off a 850w psu with an S1, thanks. |

It seems to be blowing its own trumpet a bit: Environmental:

These miners seem really interesting. Thanks for posting this setup guide also. I remember the U1, and they came a far way in terms of hashing power.

USB hub received, I hooked it up to my power supply, plugged in one U3 and it worked just fine. Plugged in the second and ERROR. Quit and restarted with them both plugged, more ERROR. They both hash together at about 30gh each (down from 59 alone), but with constants errors as below. So what else could it be? (I unplugged one USB toward the bottom, I think that's what the last 3 lines are starting to show)  |

Is that a powered USB hub? |
