That's odd, but I know I have had something similar with a Fury stick, it doesn't show up, but is still recognized by e.g. Bfgminer.
Try to download USBDview:
http://www.nirsoft.net/utils/usb_devices_view.html

It shows all devices, even "hidden" ones and if active or not, etc. You can easily delete drivers there. Might help to restart the install process.

Yeah, I'm getting the same issue.
It shows up fine in the Device Manager before Zadig:

and after Zadig:

But either way, the antminer version of cgminer won't detect anything:

The first attempt was with the U1 plugged in and the second attempt was with it removed from the system.  In both cases, it's only detecting 4 USB devices total.

I have tried uninstalling all of the drivers and reinstalling them, as well as rebooting the machine, but no matter what I do, I can't get it to detect even just one of them (I have 2).

Does this guide also work for running multiple U1 on a hub? say like 10 U1?

I tried the Zadig  for cgminer and rebooted etc but still wouldn't see the U1 so that's why I resorted back to bfgminer because you can add it manually.

Thanks for the response

If you got it to work with BFGminer then you must have at least the CP210 drivers installed, I guess.
For CGminer you will need to run Zadig. If you did, have you tried to restart the machine? I remember having had troubles there in the beginning as well.
And make sure you use cgminer from the github repository, not the "regular one", but I guess you did that?
PS: they take some time to come up to speed.

I'm having difficulty getting mine to work. I've followed instructions to the letter but just getting no device found when running cgminer.

Running i3 laptop 64bit Windows 7 off powered USB hub (although straight into USB doesn't make a difference)

I've managed to finally get it working in bfgminer but only getting 1.0gh/s and can't understand why.

Any suggestions please?

Thanks

Nice write-up. The only thing I have been struggling with is following:
(well, this, and that I have trouble mixing with Block Erupters, but that is another topic perhaps)


I can get my U1 to run with the special cgminer BUT: BMSC options gives me error:  "unrecognized option"
What gives?


Odd, now that I wrote this and tried it again, it seems to work... Apologies.

yes, by using the Zadig.

Am I supposed to be replacing the silabs driver?

UPDATE 8/4/14

I updated the guide to apply to S3's. Thanks for the kind emails about my previous tutorials! The S3 tutorial is here: http://www.rubicite.com/Tutorials/AntMinerS3Tutorial.aspx



UPDATE 2/4/14

I've added additional detail to the tutorial and I've also added an S1 tutorial here: http://www.rubicite.com/Tutorials/AntMinerS1Tutorial.aspx


UPDATE 1/21/14

I strongly recommend that you use BFGminer for Antminer U1's. The tutorial below is for CGMiner. I have made the switch. It is simpler for a single device, and it just works with multiple devices.

I am keeping my tutorial up to date on my website here: http://www.rubicite.com/Tutorials/AntminerU1Tutorial.aspx


The following is from early January:


How to Install, Use, and Overclock an AntMiner U1 Bitcoin ASIC Miner in Windows

1. Visit the https://github.com/AntMiner/AntGen1/tree/master/cgminer   This is your resource for documentation and software.
2. Download the special branch of CGMiner for AntMiner U1's from GitHub https://github.com/AntMiner/AntGen1/blob/master/cgminer/cgminer-run-windows-20131224.zip (click the "raw" button to download the zip).
3. Unzip that file into a folder on your drive. Remember the location. For this example, I will assume G:/CGMiner
4. Download the CP210x USB driver http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx - download the one for your operating system.

5. To install the CP210x USB Driver, select the x64.exe file for 64bit operating systems, or the x86.exe file for 32-bit operating systems.
6. Plug in your AntMiner U1 to a USB port on your computer. If you had already done this, unplug it and plug it back in.
7. Download Zadig for your operating system from http://zadig.akeo.ie/
8. Run the Zadig Executable.
9. Go to the options menu, and select "List All Devices"

10. Select the CP2102 USB to UART Bridge Controller (or similar)
 - Image: https://i.imgur.com/fpbtSPQ.png
11. Click "Reinstall Driver" or "Replace Driver"
12. When that is done, close Zadig.
13. Create a new text file and save it as AntMiner.CMD on your desktop.
14. The contents of this command file should be as follows:
 g:\cgminer\cgminer.exe --bmsc-options 115200:20 -o MY_POOL_URL:PORT -u MY_WORKER_NAME -p MY_WORKER_PASSWORD --bmsc-freq 0781
15. Double Click the command file. If you get any errors:
    - Confirm that your pool settings are correct
    - Confirm that the path to your cgminer executable is correct in the command file
    - If it is still not working, unplug the AntMiner U1, plug it back in, and try again
    - Finally, if it is still not working, reboot your computer and consider trying a different USB port.
16. To overclock your AntMiner U1, you will change that last part of the AntMiner.CMD file. The number following "--bmsc-freq" will change.
    - For 1.8 GH/s, use 0881
    - For 2.0 GH/s, use 0981
    - For 2.2 GH/s, use 0A81


Keep in mind that the AntMiner gets VERY hot VERY quickly when you overclock. Your must add additional cooling to your device. I recommend a strong fan blowing cool air directly onto your AntMiner U1.
