SOLVED! I just had to add:
    --usb 2:5,2:4
at the end of the command line..

Thank you -- today I downloaded the master, and compiled it. So it is the most recent version.

./cgminer -h | head will show what you are running.
./cgminer -n will list the USB devices.
./cgminer -D --verbose (followed by your other options) will show debug of it running.
... and lastly ... the README says how to setup access to USB devices if you are not using root.

Many thanks.. It seems cgminer finds a third device that it keeps trying to use..

# cgminer -h|head
cgminer 4.9.2
Built with icarus mining support.

# cgminer -n

I guess I need to somehow specify which devices to use.
Many thanks, -turgut

Um...I thought 4.9.2 was the most recent? Looks like he compiled 4.3.3?

Hello and thanks for your answer, but with the 4.9.2 is the same, i have read for the Bitfurys are the 4.3.3 the most recent!?

About the difficult, i mine with the Bitfurys only the "eMark"...

Use: --usb 2:*
If they zombie and revive (or if you pull one out and hotplug it back in) they'll be on the same Bus number (2) but get a new Device number.

Always use the most recent. There is no way 4.3.3 is "the most recent".

You probably just have a failing device. These things have a life expectancy.

Great tip; many thanks!

I was working on another project and came across this API Style guide, re implementaion of the cgminer API -  pertinently Collection Resources

Just a thought ....

It's not an HTTP server and never will be.

It's designed the way it is on purpose.
A miner's MOST important feature is it's performance when mining.

The API socket is low level and as simple as possible yet contains the information required without burdening the computer by wasting resources that may be scarce and wasting it's time matching up to the other 10 million other random formats that each person prefers.

Tacking on other crap like proxy servers and web based interfaces are design flaws that clearly certain other people have no idea about design and performance ... (not referring to you)

I was actually thinking more of the styling of the API commands than turning it into an http server ... but as usual you clearly had that covered. Its becoming clearer to me, though, why manufacturers that ship cgminer on their rigs more often than not do not ship the "out of the box" API, despite it having all the required information.

They do ship it as is (mostly), only they have stupid ideas about changing the names of fields and changing the format of fields unnecessarily and breaking compatibility between the different versions.
Bitmain even did that to their own versions on the S1.

It's nothing to do with API interface design changes.

That's the issue with the Bitmain version, they didn't change how the API works or the data format, instead they messed with fields making it no longer backward compatible, rather than simply editing the display scripts to display the raw data differently.
They already do edit the display scripts, but instead of e.g. editing a script to divide by 1000, they modified the cgminer API to do the division by 1000 and renamed the field to something else and deleted the old field name. Clearly they had no idea about design and keeping compatibility when they did that.

I guess the main problem was the fact that Bitmain copied the miner OpenWRT code DIRECTLY from Xiangfu at Avalon and then clearly had little idea what they were doing with that code initially.

All good .... banish the thought.

Hello,

Got an U3, trying to make it work but no success yet (windows 7/64) with cgminer 4.9.2

message:

--bmsc-options: unrecognized option

same with bmsc-freq and --bmsc-voltage

here is my .bat:

cgminer.exe --bmsc-options 115200:0.5 -o stratum.*** -u *** -p *** --bmsc-freq 0B82 --bmsc-voltage 0800

pause

CP210x_VCP_Windows,Zadig installed

Any idea please ?

with another cgminer, device not found

[kano]

There are no --bmsc-* options in cgminer.

Current cgminer is 4.9.2 so ./cgminer.exe -h will tell you that at the start of the output

As I've said above on this page:
./cgminer.exe -n will tell you what's connected

Also, cgminer doesn't require any settings for the miner for normal running.

Simply try: cgminer.exe -o stratum.*** -u *** -p ***

If you want to change options then read the README for the U3 options:
https://github.com/ckolivas/cgminer/blob/master/README#L338


If want to use some other miner, not master cgminer from us, then you'll need to find who made that fork and ask them.

[Hegemon]

A bit better but:
No device detected even after Zadig.

a question 

why does when a miner go zombie does cgminer not always drop the connection to it and search (hotplug)
a new (another) miner.
it will keep the connection to the miner (usb) and just set there doing nothing.

just wondering...

It already resets some devices ... something that you'll find non-USB mining software doesn't do.

But it can't physically pull the miner out and plug it back in.
Physically unplugging it acts like a hardware reset coz the miner itself is not very well designed or made on the cheap.

An example of one that works with zombies is the hashfast hardware ... oh well.

just couldn't figure out why sometimes (12 U3s) cgminer hotplug one that had gone zombie giving it a new number  and other times it would just let it set there in zombie state needing to have the usb cable unplugged and plugged back in.

Yes the U3 hits the top of the list for badly designed mining hardware.
(that ignored most of https://bitcointalk.org/index.php?topic=294499.0 )

The Icarus code does reset it - but it doesn't always fix it.
There's also no way to get any status from it other than 'it mines'

Going zombie and then getting a new number means the device itself effectively lost connection on USB and the OS reconnected it as a new device once it came back to life.

Check out the ASIC README file and use the appropriate U3 commands (--au3-volt --au3-freq).

Hi,
Can anyone please give me the link to ck try your luck at solo mining BITCOIN plz? The thread that tells you how to solo mine to your wallet at his pool. If you hit a block it's yours.
