I'm trying to setup an asicminer block erupter on cgminer 3.1.1 on Windows 7 x64.
I have a .bat file that looks like this:
C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

I have installed the drivers for the block erupter, and I can see it under devices and printers.
When I run cgminer, it looks like this:

Does anybody know how to fix this?

First make sure your hub has enough power if you're using one.  Try just plugging it into the computer.
Second use the latest cgminer (3.4?) and the zadig drivers.  There isn't any -S type stuff anymore.

Since its windows,

Switch up your slashes up:

C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

Try this:

C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S \\.\COM3


Note: I had to use CGminer 3.3.1 for it to work properly on my windows machine. No idea why

If you are still having issues (although, it seems the problem should be fixed) then try watching a few tutorials on youtube. Try to follow them step by step and you should be able to get it up and running. Try to find a tutorial which has your operating system etc.

Please let us know if you get it working.

Unfortunately, I still haven't been able to make it work. Cgminer version 3.4.1 isn't able to detect the usb miner, and switching the slashes produces the same error.

Try Using CGminer 3.1.1 - I Just realized I made an error from earlier.

What happens when you launch the batch script?

It returns the same error as when the batch script is launched with forward slashes.

Also, I attempted to use bfgminer, and I got the error "Do not have user privileges required to open \\.\COM3"
My batch file for bfgminer was this:
c:\bfgminer\bfgminer -o [pool]:[port] -u [username] -p [password] --disable-gpu -S all

When you tried the newest cgminer did you use the zadig drivers and no -S or -icarus switches?

Check the connection, is it plugged in properly?

Other than to verify the COM port your USB stick is on..As said for me, I had to use CGminer 3.1.1 for it to work properly on my win 7 machine. 

Did you download the proper driver? I have seen it confused with a "WINUSB" version.

You def. want this driver:

Here is a step by step guide (mind the slashes):

The newest cgminer just says "no devices detected", and I did install the zadig drivers.

The computer does detect the USB stick though:

was having the same problems....finally tried bfgminer....been up and running perfectly for 15hrs

I tried bfgminer, but I got the error "Do not have user privileges required to open \\.\COM3".

did you try running it in "administrator" mode?

I didn't need to resort to that, but I found numerous threads where that was advised.....

What ABN said,

Left click and highlight your batch>right click> Run as admin

When running as administrator, I still got the same error.

have you tried running bfgminer without specifying the com ports?  I typically only have to use the -S in older versions of cgminer....bfgminer has been no problem with just the address, user:pass combo

I tried it, it just says "All devices disabled, cannot mine!"

sorry we aren't being of much help....  the only other thing that I can think of (which didn't happen to me but I read about in a few places) is that USB3 ports cause issues sometimes... possible to try on a USB2 port? 

Yeah, it is plugged into a USB 2.0 port

If you're trying with the latest BFGMiner 3.2.0, then try using -S erupter:all.

Also the permissions issues you're having occur often if you're trying to run BFGMiner directly from a folder under the desktop or the desktop itself.  If that's the case, try putting it in a folder directly on C:\ instead like C:\Mining\bfgminer.exe

Also, if you want to try CGMiner again, try uninstalling the serial drivers first (the ones that identify the erupter as a COM port) from SI labs before you reinstall Zadig drivers.  You shouldn't see CP210x bridge anymore.

For CGMiner, I tried uninstalling the SI labs drivers, reinstalling the zadig drivers, and then reinstalling the SI labs drivers, but I still get the same errors.

Do you have another PC or laptop you can try?  I was unable to run my erupters on my windows7 64bit desktop but had no problem with my windows 7 netbook.

Yes, I'll try it on another computer once I get home.

You shouldn't have both zadig and the other drivers installed.  Just use the zadig.  Are the devices showing up properly there?

When I have only the zadig WinUSB drivers installed, the miner isn't assigned a COM port.

have you tried Bitminter? I had some problems, but with Bitminter I've seen all my 10 block erupters and now I'm mining from several days!

That's right, that's why you don't use the -S option.

You can download the Eobot software, it automatically will work with an unlimited number of the Asicminer USB...you can choose BTC/LTC, and it will mine either one for you using the USB.  Here's the link:

I tried bitminter, but I got a timeout error when trying to probe the port, and I do have the silabs drivers installed.

Without the silabs drivers, I still get the same "no devices detected" error in cgminer.

Did you try a different computer? Where are you located? Maybe someone could make a house call or do a remote link...
