How long for shipment to Asia?

Yes it's somewhat of a risk but I shipped the majority of the units I sold both domestically and using Priority Express International (mostly due to one huge order for more than half of my units, haha)

sorry  

I hope them to arrive tomorrow on friday, always hate it when it turns out to be monday :p

Will update when I get my big box of Dualminers :]

yea that really sucks doesn't it, now i'm having trouble trying to get as many 49 port hubs asap.

they have the 49 port hubs in stock
I have used them for several months and they have always been good to me.  Website is a little cheaper than their Amazon store.

Got my USB today. Thanks for the fast shipping / order processing, Mitty. 

Seems to be unable to mine just in LTC mode, mines both just fine though. I'll tinker with it over the weekend.

No problem, glad it got there quickly & safely.
Did you make sure you set the tiny switch on the unit itself to "L" mode for Litecoin only?
Let me know if you still can't get it working and I'll contact DualMiner for RMA info right away.

Yeah, I made sure it was set to L.

Everything installed fine, pool info is correct, all the basic stuff I checked.

I can set it to mine both, switch it to B, and it'll work no problem. Set it to mine both and leave the BTC pool info blank and it'll mine just LTC fine. I can even set it to mine both, leave the switch on L, and it'll mine only LTC but KH/s is exactly as if it were mining both.

Set it to LTC only and it won't mine at all. I haven't found a way to get it to mine only LTC at the expected ~70kh/s.

I'm sorry you're experiencing issues with your miner. :/
I just emailed my contact at DualMiner and will get back to you when I hear back from him regarding warranty claims.  Hopefully I hear word back by tomorrow.

received my stuff yesterday...thanks for the fast shipping, you are a really reliable seller and this was a fantastic group buy.

Here are some pics of my setup:










I got in late last night so i only managed to test one miner running in litecoin mode. It clocked a stable 68-90 kh/s
That was on my laptop running windows 7 x64

I tried to install in on my desktop Windows XP x84 but it crashes every time windows goes to install the driver. I installed the VCP from FDTI website like the www.dualminer.com guide said. I get the following error message: "driver download timed out"

Any ideas, Mitty? I will try again tonight and post some screenshots. Is there a place to download the drivers manually? that would be a lot easier...

Will let you know what speed i get running 30 of them on Dipo Electronic 19 port hubs. These hubs have a lot of juice in them they can deliver about 1 amp per port easily so that should help.

I figured it out! I don't think the issues are with the USB, to be honest.

I went to the install directory, changed and ran the LTC_ONLY.bat file. Raised the setting "--dualminer-pll 500" to 900 and it's now hashing at ~70KH/s.

It will not work if I use the GUI that installed.

Awesome, glad it's working!
DualMiner just got back to me and said it doesn't sound like a hardware problem, haha.

I experienced a similar issue when I tested a few of the units and had just assumed it was something wrong with my computer;
I first tried running a few units on my Windows 7 x64 desktop PC with no success- drivers seemed to install but the units would simply not mine.  So I then tried on my Windows 8 x64 laptop and they worked fine and assumed the issue must be with my desktop PC.

However according to the DualMiner site you don't need to install the VCP driver unless you're on Windows XP- Windows 7 and 8 should install the devices automatically.

Can you post some screenshots of the errors you're getting?

got mine in the mail today!


thanks Mitty

Ah didn't realize that.  Glad you got some hubs coming.  Wish I had got more than 3 of these from Mitty.  After setting them up they mine great so far.

I sorted it out in the end. It was a problem with the operating system. Turns out the computer was using Windows Vista (maybe there is no support for Windows Vista?? on the dualminer website it only talks about Windows XP, 7, 8 and 8.1).

Anyway i upgraded to Windows 7 and then tried again and they installed the drivers automatically, no problem.I have 30 hashing away now at average 1900 - 2300 kh/s. Appear pretty stable for the time being. Any info about firmware upgrades for the single chip miners? There is suppose to be a firmware upgrade for the 5 chip miner that improves the speed from 300 kh/s - 500 kh/s.

Also do you plan to have any more stock soon?
