[ANN] Introduction to DualMiner USB (could mine both BTC and LTC)

[BartmaX]

Will You ship to Europe?

[sbfree]

Can someone please tell me how to get this working. I use cgminer and cgwatcher. thanks

I think you'll still need to use the special fork they have with the download. If you look in the installation directory you should see the special version of cgminer.

Though I sent a PM as well:

when I installed the application from dualminer.com

First the drivers: http://www.ftdichip.com/Drivers/VCP.htm
Then the application: http://support.dualminer.com/wp-content/uploads/2014/01/DualMinerSetup-1.0.0.6.zip

Then I looked at where it installed it on my machine:
C:\Program Files (x86)\Broadeng\DualMiner

In there should be a directory called:
cgminer-win-32bit-2014-01-24_154358

That's the version, that I used to get it to work from command line.

To make it easy, I just modified one of the existing batch files which was already there

cgminer.exe --scrypt --lo -o stratum+tcp://us-east.multipool.us:7777 -u dmpotter.dual -p x -S //./COM22 -S //./COM23 -S //./COM24 -S //./COM25 -S //./COM26 -S //./COM27

Now, keep in mind those COM numbers came from:
Device Manger and under Ports (COM & LPT)
They were listed as USB Serial Port (COMXX)

It's not the standard version of cgminer. I wish I knew how to bring up the normal GUI mode and not just API.

Strange...I thought CGminer used Zadig only   FTDI is used by BFGminer,did they switch over or use both now

i thought i read somewhere that these run hotter mining LTC/scrypt, which doesn't make sense to me since I it uses less power.

Any noticeable heat issues? thanks.

[daserpent1]

Is shipping to India at all possible?

[BFGIRL]

Sending in Japan Is it possible?
At the same settlement only bitcoin?
Bank transfer, Paypal, credit card is impossible?
I not have a bitcoin!
I need your help by other than bitcoin!

These usb in scrypt mode are not hot at all.

These usb in scrypt mode are not hot at all.

so these should run any scrypt no problem right....I saw Dualminer state that these might not support DOGECOIN, could that be right?

[dmpotter]

The developer only provides support for Litecoin, but it does work with all scrypt coins.

[fastcore]

Pretty excited to try these

[Blaater]

I've been trying it out for a while, even running a small rig with it on leaserig.net but.


It's pretty unstable for me.
The API in the CGMiner version is having difficulties.
I often need to close CGMiner and start it up again to get it properly working with the API.

[ManeBjorn]

I have been using mine and it works great.
So far I have mined LiteCoin and Doge with no issues.
It run so cool in LTC only mode.

I do have a question?
Are there commands to overclock much like others that you can change osciallting bits?  It runs at such a low temp with no active cooling and even better with a fan I bet we could easily squeeze a bit more out of it.

Without doing anything it run about 75kh/s solid.

Thanks excellent product so far.

I am not able to get this to work. I also tried:
cgminer.exe --scrypt --lo -o <URL>:<PORT> -u <USER>.<WORKER> -p 1 --dualminer-pll 400 -S //./COM50

Can you do " -S all "?

You cannot do '-S all'. However the GUI allows an "ALL" feature.

Are you sure you have the right COM port? There will be two that show up. To verify which one is which you can
run the gui in LTC only mode and see the output of cgminer to see what COM ports it shows up as working.

Also I didn't use the --dualminer-pll option.

[lajz99]

Does anyone have these up on MinePeon yet?

[stex2009]

and,  can't mine on other pools too. i am using
https://coinex.pw/mining/pools/DOGE

[sbfree]

Working perfect so far on Fast-pool making Dogecoin, and they run nice an cool and even cooler w/ a fan.

[stex2009]

They work perfectly on a 49 port hub. I just tested 10 of these.

It's strange, that I was able to run 10 BE USBs on this computer (I have 10 USB ports on the computer) with no issues, 6-7 antminers I remember with no issues, but this computer will only take 2 dualminers at a time? it doesn't recognize any more after that. Do they take more power? I was just running them on LTC mode.

[ManeBjorn]

Just wanted to share that on the LTC Rabbit website a couple users are going nuts saying it's a scam.  I even got called some pretty crazy names which is surprising as usually people there are nice.
I even posted pictures.
I can say it is not a scam.  It works great.

[ManeBjorn]

I only have one to test but I have seen some others say they had 5 or more running together.
It does not mean I am correct I may have misread.

I am able to run them on my multi port hub (separate hub with separate PSU), no issues at all running 10 of them together.

I meant, my computer (and 10 usb ports on my computer itself) handled 10 BEs very easily. But can't handle more than 2 of these. Was wondering why! Can it be the power issue? Do they take more power as compares to BEs ?

[ManeBjorn]

Not sure on that.  It could be they draw more power but in LTC mode they seem to draw very little and run cool. 
I bet if we get the info we could overclock them easily and keep them cool with no problems.
