I've been able to get my 48 miners powered by a single windows x64 machine. I was using anker 13 port powered hubs and I found that you can't daisy-chain them, as windows sees each block of 4 ports as a daisy-chained "hub." Basically, you need to plug each hub into the machine or, at the very least, daisy-chain off the first port. Here is my current setup, minus a few gridseeds. When I initially plugged these units in, I couldn’t get windows 7 x64 to see the virtual com ports, and found I needed to install the virtual com driver that I found here: http://www.diffpair.com/lightningasic/LIGHTNINGASIC%20Gold%20miner%20USB%20driver.rarI’m running separate instances of the custom-coded cpuminer with the BTC core shut off for scrypt-only mining. I was able to get that from here: http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/I have been able to get about 16 mh when mining with 49 of these units. I’ve been running them for 48 hours straight now with no disconnects, no reboots, and 100% stability. If you are having issues with the supplied controller, I suggest you ditch it and use a computer. If you’ve still got motherboards lying around from your GPU mining days, setup a quick install of windows/linux and run your gridseeds off that. PICS:

Then once you've gotten this done, you need to create a couple scripts that will help you run the cpuminer instances. first, called mine.bat: echo on miner-start.bat stratum+tcp://us-east.multipool.us:7777 The next one, called miner-start.bat. Note--if you are running more than 10 COM ports, you'll need to slightly modify the COM designation in the script from COM12 to \\.\COM12. start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM2 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM3 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM4 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM5 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM6 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM7 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM8 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM9 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=\\.\COM10 --url=%1 --userpass=zeetak.1:x start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=\\.\COM11 --url=%1 --userpass=zeetak.1:x Now when you run mine.bat, you'll open up xx instances of minerd and will start hashing away. My next step is Windowskey-D to minimize everything, then maximize just the windows you need. As you can see, the amount of system resources it is using is hardly any, so it shouldn't be a problem to run 50 instances on your desktop:

Awesome. Fed-Ex just delivered my 20 pack, now I just have to try and sneak out of work for a few hours to get them going.

VERY HELPFUL I forgot that batch file trick in passing the variable.
Also your hashrate looks a little slower that I had expected it to be, although I don't know whether you are running all 50 but 15Mh was what I would expect

Have you considered running it as a service? Would certainly clean things up if you actually want to continue using that computer while mining! (not to mention you don't have to worry about when the computer crashes and/or reboots while you're away).

Will there be a way to monitor random miners here and there if it's running as a service?

many many thanks for your quick "how to". I'm actually waiting for my LA6M and was afraid to have some faulty controller comming with it. wouldn't it be possible to use a standard atx psu with those barrel connectors? 12v should be equal but i've no clue about the rest.

Hello !
I know that Gridseed can mine only for scrypt based coins at the full speed. Which particular coin worth to mine with Gridseed ? I mean to have at least ROI.

I wonder if windows 8 would see things different? Have you tried win 8? -bobby

He said they were anker hubs. If you look at the picture it looks like all the plugs are in a line.

I know that some people have contacted the user "cablez" to make them pci-e 6-pin adapters for barrel connectors.

You are right. I had a few units that weren't hashing, thanks for mentioning that! I looked and they were connected to bad cables. Now i'm running 49 units at 16,148 KH. Is there any way to overclock these? Mine are running at 850mhz, and I heard that when people pushed them up to 900, the hashrate dropped. Perhaps a new firmware? After a day of these units running I got sick of the noise of 49 small fans, so I disconnected the individual fans and pointed a box fan at them. Now they are running silently and are only slightly warm to the touch. The only sound is the power supply fans kicking on every once in a while.

Also--it looks like somebody has gotten cgminer to work in LTC mode with BTC disabled so you don't need to run cpuminer. Here's the comment:
