Zadig can be a pain for some.  Did it say successful on install?  You might try again.

Also long term a RPI or R1 is best to control it as does not take a big computer to run.  So might look into that longterm.

With cgminer started unplug the usb cable and plug it back in and wait a bit.

You also might look into devices and see if you see it.   Make sure it is not detected by pc and cgminer problem.

What version of Windows are you using?

it's detected by pc. cgminer using 4.8.0. cgminer.exe --bmsc-options 115200:0.65 -o stratum+tcp://mint.bitminter.com:3333 -u a.1 -p X --bmsc-voltage 0800 --bmsc-freq 1306.

using windows 7 64bit

Might try with less and see what it does, then go deeper into commands to fine tune after detection.  It's been a while since I ran my U3's on windows so this could be right or wrong.

But for detecting see what this does:

cgminer.exe -o stratum+tcp://mint.bitminter.com:3333 -u a.1 -p x --suggest-diff 144

See what that does for you if you then have U3's showing up or still nothing.  Been a while since I used Windows with them R1 with CrazyGuy's firmware mod is honestly one of best controllers.

When detected by the pc does it show the proper driver, i.e. did Zadig work?  Run Zadig a few times, unplugging and replugging the U3 between each time.

Also, try cgminer 4.9.2 and use the updated --au3 tags.

Try going here: http://hakedev.com/wp/2016/01/06/setting-up-your-antminer-u3-in-windows-8-1-updated-2016/

A guide I've used before, pretty straight forward.

Also for overclocking definitely use --au3

--au3-freq <arg>    Set AntminerU3 frequency in MHz, range 100-250 (default: 225.0)
--au3-volt <arg>    Set AntminerU3 voltage in mv, range 725-850, 0 to not set (default: 775)

And last, use the latest cgminer.

So if you go into your Device Manager do you see the device?

I'm thinking devices and printers shows them to.  If set up properly they should show up in there ( I believe it tells com port in that view aswell).

I think he might look at Zadig if not working still. I think it was most common problem.

the picture is for antminer u3. it's make me confused.

He was joking on ant's.  But your image is far to small to see anything.  Pull it up and it is tiny... unreadable.

Try uploading to different site or something as that will not help.  Below is size you have it at...

What is the exact command you are using to start cgminer? Also have you updated to the latest version of cgminer?

Are you running cgminer from a .bat file or are you using the command line?

You should really be creating a .bat file in your cgminer directory and adding this line to it:

cgminer.exe -o <YOUR POOL> -u <YOUR USERNAME> -p <YOUR PASSWORD>

THen once cgminer starts, if the u3 doesn't show up, unplug the USB cable and Plug it back in.

Also you are power these with a PCI-E cable correct?

I suggested a basic one a bit ago - https://bitcointalk.org/index.php?topic=827356.msg13546056#msg13546056 don't think it was tested.  It is a good way just to see if cgminer sees it.  And use latest cgminer I believe.

I am thinking about selling a R1 possibly... if anyone is looking for one to control a U3.

try this.

Now we're talking !!

USB implementation on the U3 seems to be a bit flaky anyway. That's quite obvious if you read this thread. I have two U3 connected to my GNU/Linux Box and that works without too much problems (they do zombie from time to time though). There was no need to install any additional drivers. Maybe that's an option for those who can't make it work under Windows.
