Re: How to use ASICMiner Block Erupters with CGMiner on Windows 7

...
Note that I saw a post from one of the cgminer authors suggesting to use 115200:2:1 and 3.0=80. When I did that, I got errors and cgminer immediately crashed.
...

Yes I posted ~~115200:2:1~~ on the first day I got it almost 3 weeks ago and then corrected it that day Tongue

As you used, you would only use 115200:1:1

3.1.1 still requires the windows serial driver for Icarus devices (but only for Icarus and Avalon devices)

3.2.0 will not use any serial drivers and you must use zadig to set the WinUSB driver for them (3.2.0 will be released shortly)

3.2.0 auto detects all supported USB mining devices and auto hotplugs them all also.
It sets the --icarus-options and --icarus-timing performance numbers automatically for each device also - but you can override them of course.

The Asicminer USB (Block Erupter USB) shows up as "AMU" i.e. AMU 0, AMU 1, AMU 2 ...

i've yet to see 3.2.0 work for me... it does not detect anything... i'm still running bfgminer instead.
would like to get cgminer 3.2.0 working though

3.1.1 works fine with the info I posted above. I can't get 3.2.0 to work either. Some people seem to think it's USB 3.0 hub related.

Yes USB 3.0 is certainly on the top of the list for problems (that I'll need to sort out shortly)

Also the initialisation error (4) I've yet to be able to reproduce the cause for me (and work out a fix)
So certainly for windows, for now I'll say 3.1.1 while I try sort out solutions to problems being seen.
On linux, if 3.2.0 just works, then go with that, if it gets initialisation failures, use 3.1.1 for now until I can sort out that error.

On linux the switch from 3.2.0 back to 3.1.1 just requires you to stop cgminer 3.2.0 and then unplug+replug the USB devices.
If you run USB on both 3.2.0 and 3.1.1 at the same time, it will cause problems.
