I received my order but I am unable to get it to work properly. On cgminer 3.0.1 I am able to get 6 devices up and running (the number of Cairnsmore1's I have)... but they only has around 380 mh/s regardless of any timing settings I use.

On 3.2.0 cgminer with the new USB rules, they do not detect at all.

I've tried 3 or 4 different modprobe lines some which don't work at all and some which seem to half work...

It seems like its only using half of the chips on the CM1's and I can't figure it out.

As an update to my own post, I am able to get 5 out of the 6 units to work properly using an old cgminer (new one still won't work with them) and using this modprobe line:

Code:
modprobe ftdi-sio product=0x8350 vendor=0x0403

However, one unit fails to mine and has 2 orange LED's on while the others are mining. Before mining starts all the LED's on it match all the others. The dip switches match the others, so I can only assume something is wrong with this particular unit. I've swapped USB cables and ports and the problem stays with this CM1 unit.

Ideas as to what to try?

Just a few quick thoughts:

Have you tried running cgminer as root? There is some sort of issue IIRC with USB as non-root.

I use icarus timing long, but I don't think that's a problem here.
I use modprobe ftdi_sio product=0x8350 vendor=0x0403 too so that can be ruled out.

What happens if you _only_ connect that single one you think is faulty?


Edit: Do you see them all with
Code:
ls -l /dev/ttyUSB*
?

Running as root it does the same, linux sees them and the USB devices are created but neither cgminer or bfgminer will recognize it as an Icarus/Cairnsmore device.

In my /etc/rc.local file I have this:

/sbin/modprobe ftdi_sio vendor=0x0403 product=0x8350
sleep 1
echo "0403 8350" > /sys/bus/usb-serial/drivers/ftdi_sio/new_id
sleep 1


-- edit

And you'll also need to add the user whose account you run the miner application under to the "dialout" group.

You didn't hit that road block yet, but you were probably gonna soon.  Smiley

thanks!
i did this:

also in my local.rc i have


modprobe ftdi_sio vendor=0x0403 product=0x6014
modprobe ftdi_sio vendor=0x0403 product=0x6001
/sbin/modprobe ftdi_sio vendor=0x0403 product=0x8350
sleep 1
echo "0403 8350" > /sys/bus/usb-serial/drivers/ftdi_sio/new_id
sleep 1


i have also a BFL that works ok. and some icarus boards on their way but the CM1 doesnt pick up.

now it shows up as

[edit] Looks like you're making good progress then.

The CM1 still doesn't get an assigned /dev/ttyUSBxx   ?

Does it show up with an "lsusb" command?

And I'm not sure from your statement above, but do you have the CM1 plugged into the USB before the modprobe and "echo ..." commands are issued?

Well now you've gone past where I can be helpful since I'm using neither cgminer nor bfgminer.

You'll need to start searching to find more info about those specifically.    Sad

Lots of people have been having problems with cgminer 3.2.x. Hope you're using something slightly older than that.

--

I'm using Modular Python Bitcoin Miner (MPBM) since I found it does better with the dynamic clocking flash on the CM1's than bfgminer did. I also have a BFL FPGA hooked up in the mix driven with MPBM.

BUT, since you don't have the dynamic clock flash on your CM1, I assume - they don't ship that way, you will probably get slightly better performance with cgminer or bfgminer.

K
swapped to MPBM

but the workers dont start.

the only error i see is
Code:

In the "Worker editor" you are supplying the "Port:" as "/dev/ttyUSB1", etc.?

-- edit

Also, I'm sure you remembered to stop any executing instances of cgminer or bfgminer which were previously running.

-- edit

And let's double check those permissions down in /dev

In my last post I have an alias for ll='ls -la', if that wasn't obvious.

If you put a screen cap in your last post, I'm not seeing it.

Well that looks effectively the same as mine.

My BFL Single is on another machine ATM doing some testing, so 0 - 7 is both my CM1's.

AH, here's a thought, with my flash each FPGA chip gets its own comm line / USB port. But, IIRC, with the standard flash things are substantially different.

Have you tried stepping through one at a time?

I.e., try only one worker at /dev/ttyUSB0 .
If no joy, delete that worker and try /dev/ttyUSB1 .
etc.

Also, are you creating icarus workers or cairnsmore in mpbm?

Got the image. Looks as I would expect.

And you might give a try stepping through the USB ports one at a time as an icarus worker.

Though I doubt that is the problem of the moment since you are getting a failure to open port.
Not some sort of 'unexpected reply'.

And here's another thought.

I have encountered problems with my CM1s if I don't bring them up in the sequence they like.

1) Computer and USB hub on but MPBM not running
2) disconnect CM1s from USB
3) power down CM1
4) power up CM1 and wait for it to be fully stable
5) connect CM1 to USB
6) verify /dev/ttyUSBxx are present for the CM1
7) start MPBM

Now, this just might be an issue due to my running a more experimental flash than the stock flavor. But it is what I've had to do.

Key step: Never connect the CM1 to USB until it is fully powered up / stable.

But one last note.

As you know, the rPi is a minimally powerful machine. It cuts it with MPBM, but just barely.

For example:

running the BFL Single with MPBM on the rPi lightly overclocked to 800mhz the BFL settles down to an "Average MH/s" of 787.xx.

running the same BFL Single with MPBM on a quad-core 2.66ghz Mac Pro it settles down to 794.xx.

Almost a whole 1% faster.   Smiley

I can't give the same comparative values for the CM1s since I could never get them to work on OS X.

-- edit

I mention this because either cgminer or bfgminer will put less of a compute strain on the rPi. And since you're running the stock CM flash you shouldn't really *need* to be running MPBM. (Unless you just prefer it. Which I happen to. In addition to MPBM running the dynamic clock CM better.)

-- edit 2 (And one more thing.)

I've also found that MPBM on the rPi runs just a small bit better / faster if I set it up with GetWork "Work Sources" running through slush's stratum proxy than by using the built in stratum Work Sources.

YMMV.
