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

[likeBTC]

do these work with mac osx ?

No.

[Dabs]

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.

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

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

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

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.

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...

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

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..

post a screen capture, which may give some details ?

..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.

I have an issue where my dualminers stop hashing in the middle of the night, I leave them at work so by the time I get in the office to reset them I've already lost precious mining hours

http://imgur.com/HmfeMsd

it looks like it's still connected to my pool, but my miner's status page on wafflepool says 0.00kh/s and it's not accepting any new shares.

Im running it via batch file as the dualminer software gives me too many HW errors (10% or more)

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

[dyland]

selling these units for $35.00 per unit.


pm me if interested.

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

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?

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.

[Hektek]

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

best regards

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  ...

I keep getting the error :

 cgminer.exe: -S: unrecognized option

Any help?
