Topic: [ANN] Introduction to DualMiner USB (could mine both BTC and LTC) (Read 114581 times)

What command line options are you using? Maybe you're just imputing them wrong, have you checked the help file?

I keep getting the error :

 cgminer.exe: -S: unrecognized option

Any help?

I isolated one out of my five dualminers that was real troublemaker  . It was capable of messing all other (different) usb miners at the same PC under WIN showing usb and comm errors  . Now, it is on his island (directly connected to the USB port of one server PC mining ok by himself  ) and the rest of dualminers are happy mining at 875 frequency together with Gridseeds  ...

Is there an img for raspberry pi to let them run ?

best regards

I got COMS errors all the time. I honestly think it is the version of windows I was using. Vista it sucked at, but older versions worked really well...


edit: oh and a high quality powered hub definitely helps if you have a few of them.

I'm liking these little things but I keep getting problems with it.  I start it up and it runs fine for a few minutes at almost 70k, then after a mere five to ten minutes I get this:

DM0: Comms error
Failed to open dualminer pn //./com158

DM0: comms error
DM 0 failure, disabling!
Thread 0 being disabled

Then it stops accepting and my hashrate drops to half, then to half of a half, then to half of that half, and so on.

Saw this mentioned earlier in the thread but didn't catch the answer.

Anyone know if I just need a hub for them to work best, or is this a diver issue?

Hello,

I just got dualminer 2  and I'm running Linux Ubuntu 14.04  and I built the cgminer-dualminer 3.5 and everything works fine but according to cgminer my 1 dm2 is

  [2014-05-21 07:54:44] DM0                | (5s):217.7K (avg):92.02Kh/s | A:832 R:0 HW:0 WU:1.5/m

sometimes the Kh/s goes up to 300+ the stats above was  for 7 minutes.  And  my dm2 gets really hot, like almost burn your hand hot.
Does anyone know if this is normal?   I have a sony laptop and the dm2 was plugged in directly to the usb 3.0 port.   Thanks! 

Also here are my config settings:  ./cgminer --scrypt -o stratum+tcp://mypool.com -u xxxxx -p xxxxx

selling these units for $35.00 per unit.


pm me if interested.

I'm having the same problem. ( see imgur screenshot above)
Has anyone found a solution to this?

I'm running this command:

/opt/dualminer-cgminer/bin/cgminer  --dualminer-pll 850   -d0,1,2  --scrypt  -p z -u 1CLjKuuyvgaHEKQfcUxoPenYgXViFyNiF5 -o stratum+tcp://uswest.wafflepool.com:3333   --remove-disabled  --api-listen --api-allow W:192.168.0.0/24 --api-port 5028

 DM 2:                | 56.89K/60.49Kh/s | A:2048 R:0 HW:0 WU:0.7/m

..just to prove I'm running a version of cgminer that supports the --dualminer-pll argument:

# strings /opt/dualminer-cgminer/bin/cgminer |grep dualminer |head -3
/opt/dualminer-cgminer/bin
--dualminer-pll
--dualminer-btc

..under a windows VM using the official software from dualminer.com I also get around the same speeds.

post a screen capture, which may give some details ?

I tried one in a Windows VM and got the same speeds, again despite the frequency/pll setting.

These are dualminer2s and as a result don't have a switch to go to BTC mode so there shouldn't be any reason they are slow that I know of..

by default I get 70 khs each, never had any issues. very stable. running multiples on windows using the GUI.

What kind of hash rates are you getting on the Dual Miner 2s?   Mine are all 55-57k (sometimes spiking to 60K), for example:
DM 0:                | 55.59K/57.87Kh/s | A:59392 R:  0 HW:19 WU:0.1/m
DM 1:                | 55.59K/57.82Kh/s | A:60928 R:  0 HW:11 WU:0.1/m

Despite using the dualminer cgminer version and giving it the --dualminer-pll 850 options I am apparently unable to get the to run slower or faster, whether I specify 400 or 850, the resulting hashrate is the same.

Running this on Linux.   I wish the same version of cgminer that works on the gridseed would work on the dual miner2 as well...


 

Hi There:

Getting rid of these guys - just bought - at a loss as I have some unexpected car repairs.

PKG Deal (includes hubs and free shipping):
28 Dualminer USBs + 3 Orico ten-port USB hubs for $1100.00


I will sell individual units for $40.00. These are basically new.

Any developments for OPENWRT? (scrypt mode only, don't need dual mode)

If anyone got it working I would be very grateful for a link or a short step by step...

I would love to plug them in my router and forget about them like my antminers

I can confirm that. I am running the USB dual miner from my 10.6.8 hackintosh. Works great

They work. I am using it with my macbook air temporarily.You can see the directions here :

http://blog.nwoolls.com/2014/03/21/litecoin-mining-on-mac-os-x-dualminer-asics/

Anyone got these to work with cpuminer (Windows)? Or even cgminer without the gui?

BTW, I have one of the originals. Does anyone want it? I reviewed it on this same thread:

No.
