GekkoScience Compac BM1384 Stickminer Official Support Thread

[Jake36]

Yes, with a Pi2 B (don't know if the older Pi's will work with it or not), ran 5 sticks for a week, plugged into a USB 2.0 hub that was plugged to the Pi. Then again for a week with 5 sticks plugged straight to the Pi, with no problems.

Ok so not directly plugged but using the know workaround (which doesn't always work), but good to know.

Thank you Jake.

Now I just have to find one that ships to Europe and hope it'll handle 6 sticks :p

Or I just get another Orico A3H10 and use 3 sticks on each.

That didn't come across like I meant.

1 week with 5 sticks > in the superbpag > into 2.0 hub > into Pi2.

Then 1 week with 5 sticks > superbpag > into the Pi2. (took the 2.0 hub out)

So 2 weeks (and counting) with no trouble either way and depending on the freq you want, you should be able to do 7 sticks.

I did the 5 sticks at freq 250 on the superbpag.

that was clear, it was just me not reading carefully.

Thank you for taking the time to correct

I had a new hard drive image flashed to my computer and after the update I get the following error when I launch bfgminer with 2 sticks in a usb hub:


If I unplug the hub and plug it back in I get this:



I have no idea why this is happening after the system update, everything else works flawlessly.  Anyone have any ideas for me to try?  Thanks.

Unplug replug the hub

Try a usb memory stick to make sure it's fine

[Mikestang]

I tried unplugging and replugging the hub and I tried restarting the computer a few times.  Still gives me that error, very weird, I'll have to dig deeper.

I reinstalled the CP2101 usb to uart driver and now bfgminer will not see the sticks even without the hub (note, I did not zadig, but am getting the same result as if I did).  I am able to use both sticks in the hub on cgminer-gekko now, bfg is still running my nanofury sticks.  Guess I'll roll with it like this for now since it's working and I don't feel like messing any more with it (if it ain't broke...).

The other interesting thing is the comms error I always used to get with the sticks in bfgminer is gone now, so that's good, no more dropping hash rates and having to restart the miners every day!

i  need an expert to help me.. i got cgminer-gekko working on the r1 and i modified the lua to work with the new cgminer-api.. but i have one problem i cant fix..



if you notice, #2 is twice.. always twice.. i dont know why.. here is my code.

Code:

function stats_u3()
   local api = {}
   local data = {}
   local stats = luci.util.execi("/usr/bin/cgminer-api -o devs 127.0.0.1 4029 | sed \"s/|/\\n/g\" ")

   if not stats then
      return
   end

   for line in stats do
      for nam, val in string.gfind(line .. ',', "([^=,]+)=*([^,]*),") do
         api[nam] = val
      end
   


    if api['Device Elapsed'] then
         local elapsed =  api['Device Elapsed'] 
         local str
         local days
         local h
         local m
         local s = elapsed % 60;
         elapsed = elapsed - s
         elapsed = elapsed / 60
         if elapsed == 0 then
            str = string.format("%ds", s)
         else
            m = elapsed % 60;
            elapsed = elapsed - m
            elapsed = elapsed / 60
            if elapsed == 0 then
               str = string.format("%dm %ds", m, s);
            else
               h = elapsed % 24;
               elapsed = elapsed - h
               elapsed = elapsed / 24
               if elapsed == 0 then
                  str = string.format("%dh %dm %ds", h, m, s)
               else
                  str = string.format("%dd %dh %dm %ds", elapsed, h, m, s);
               end
            end
         end


    if api['ASC'] then
        data[#data+1] = {
            ['stats'] = api['ASC'],
	    ['Device Elapsed'] = str,
            ['GHS 5s'] =  tostring(math.floor(api['MHS 5s']+0.5) / 1000),
            ['GHS av'] =  tostring(math.floor(api['MHS av']+0.5) / 1000),
            ['Hardware Errors'] = num_commas(api['Hardware Errors'])
            }
    end
    end
   end         
   return data
end 

i cant find anything in the code that would make #2 come up twice

i ordered this USB HUB
http://www.amazon.com/ORICO-USB2-0-Adapter-3-3Ft-Desktop/dp/B00EH44AA6 and some Y-USB-Cables :-)

good to be back in home-mining

Hi guys,

I am having trouble using this USB miner,
I have used the installation instructions which is written on the second page with --enable-gekko where i used cgminer-gekko.tar.gz

Should the USB just be detected after this?
When i start cgminer i see "No USB detected" but, pressing U and then l in the menu, it says Bus 1 Device 10 ID: 10c4:ea60 bitshopperde Compac BM1384 Bitcoin Miner inactive

I have tried every combination of OS (windows/linux/osx) with every combination of cg-miner/bfg-miner but none of it works.
Totally out of clues!

Hope you guys can help me!

Thanks!

Should be straightforward in linux.

You need zadig drivers with windows/cgminer

Are you using a hub or directly on motherboard ?

Have you checked the V pod ?

Is the green LED on ?
Is the "white" one blinking ?

[Genzetsuei]

I've done hundreds of troubleshooting in linux, but this one is out of my range! xD

I'm plugging in the USB directly to my laptop. There is a green light constantly on but haven't seen the white led on at all.

What is the V-pod you were mentioning?

I am using cgminer 4.9.2 btw.

[zOU]

Are you running it at stock frequency (150Mhs) ?

The Voltage pod is to control power to the chip. (see 1st post)

[Genzetsuei]

I'm using the following to TEST:
cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 150

The v pod is pointing towards the south (opposite of usb input) which should be equivalent to 0.55v right?

[sidehack]

To run smoothly at 150MHz you probably want at least 600mV, which you can measure on the VCORE and GND test pads on the backside. The pot's flat should be at about 3 o'clock position.

[Genzetsuei]

Hmm.. I think the problem lies in detecting the USB within cgminer..

 [2015-11-24 23:01:09.253] Started cgminer 4.9.2
 [2015-11-24 23:01:09.471] No devices detected!

[Mikestang]

Did you install the cp2102 usb to uart driver?  Did you use zadig?  You should also be using the cgminer-gekko version, not 4.9.2.

[sidehack]

He previously mentioned he was using cgminer-gekko, which is built with 4.9.2 pretty sure. In any case if he tried --enable-gekko building from the stock 4.9.2 it would have thrown an error. 4.9.2 will recognize the Compac as a U3 via Icarus if the WinUSB driver is installed for the device, or by default on Linux builds.

He also mentioned that he had the pot set to 550mV, which he'll be very very lucky if the stick detects at that voltage. Maybe at 100MHz? Almost impossible at 150MHz. Though, still should see the white LED flash a time or three while trying to initialize. Flat in the 3 o'clock gets you about 600mV; flat in the 12 o'clock actually wraps it around to full voltage (about 800mV).
My test setup pulls from a laptop USB port with some current limiting, and actually if the voltage is set too high the stick won't initialize because the buck gets starved and the core voltage drops out. This would happen even with the flat in 6 o'clock position, which runs a bit shy of 700mV.

Hi, you are not alone, i have exactly the same problem with cgminer-gekko, sticks are not detected but appears in the usb menu as inactive. i dont know why . Maybe try bfgminer 5.4, it works for me.

Same situation with my stick from bitshopper. Bfgminer 5.4 has been working perfectly for me for weeks now though. Sidehack did mention earlier in the thread when I was reporting difficulties that it may be something in the gekko version of Cgminer as it was written before the Euro version was made. I'm not sure if it got investigated further.

Just in case anyone's interested and isn't watching the stick pool thread, one of my sticks did a 1B+ share today (1000065233.8890336) :



It's the same stick that won me a stick in the best share competition last weekend with an 11.6M share.

yea I have the A-300:

http://www.aliexpress.com/store/product/Cool-style-USB-2-0-HUB-Charger-10-ports-with-CE-ROHS-FCC-certification/1938705_32513481030.html

looks according to the specs only 600mA per port...sucks.

I would still like to know if there is a way in general to test the max Amp per port on a US hub manually?
Thanks!

someone said (sorry don't have the proper reference handy) that Superbpag usb 3.0 works fine with Raspberry pi and Compacs.
it has seven ports with 2A per port, apparently, for a total of 70W/14A, but costs $36, similar to 10 port Anker.

I've been looking for a good hub to mess around with overclocking this gekko (and likely more!).

This should work well - order placed.
