But I am curious what are the four LEDs for?
From the silkscreen, 3 of them appear to just be power indicators (one for the 3.3V regulator, one for the 1.8V regulator, and a separate one for the core voltage(?)), and the 4th one the usual status LED.

ok, so here's what I am doing. using windows 7.

Step-1:
Insert USB, I see this auto installation


then, it shows it's ready


Step-2:
Installed latest cgminer (cgminer-4.2.2-windows), and use this command
Code:
cgminer.exe  -o stratum+tcp://stratum.mining.eligius.st:3334 -u <USER> -p <PWD> --bxm-bits=54



Questions:
1. Can I use bfgminer?
2. Where did I go wrong? I see it says "I need to install a WinUSB driver for -BXM device". Do i still need to follow Zadig instructions even if it said the device is ready to use? i did try to run "zadig_2.1.0", but I wasn't to install anything succesfully. Please help.

So, I did "reinstall driver" and i am able to see this 1 USB I installed. Hope I didn't mess up any settings for my other devices.

So install a winusb driver for it. Follow the cgminer instructions, not whatever windows thinks it's doing.

Note: BFx2 uses an uncommon (but not bad) design which means BFGMiner will also use WinUSB/Zadig for the driver on Windows platforms.

When I run these on my windows machine, I get disconnected from my internet after a few minutes of hashing. I have tried this many times now. It is something with these devices? as my dualminers and ants and BEs always ran for days and days without any issues like this. Any tips to fix this?

(I am using a usb adapter to connect to my wifi network at home)

BFx2 support merged into BFGMiner git (Windows builds can be obtained here).
Note that since it's impossible to tell it apart from various other devices (including BFL/Cairnsmore1 miners and even many non-mining devices!), you must run with the -S bfx:all option.
I do not know what this will do with other devices; it may start fires, launch nuclear missiles (please don't run BFGMiner on computers with missile controls), etc. (this warning is true of cgminer in general btw; BFGMiner is no less safe than that)

Thats strange  Huh Huh Huh any ideas Goodney?

Is your usb wifi adapter running on the same hub? Is there a power surge or something?  Try plugging the wifi adapter into a different port.

Also it may be because your USB wifi adapter is being automatically turned off by windows for an unknown reason.

Solution:

Go to Device Manager (Control Panel\System\Hardware\Device Manager), and find the hub the wifi adapter is plugged into. On the last tab called "Power Management", disable the tick that says "Allow the computer to turn this device off to save power". This should be the thing that fixes it. If not, whilst in Device Manager, go to Network Adapters, and select Properties on the wifi adapter, and turn off its power saving options there as well...

What is the name of your usb wifi adapter?

Could also try the new compiled version of bfgminer and see if you still get the same problem.

That is indeed strange, I too am running my mining machine with 25 of these with a Wi-Fi adapter for the network. However, I am running linux.

My suggestion is to make sure the Wi-Fi adapter is on a different port, or if possible different root hub on the PC. This should separate the mining traffic from your Wi-Fi connection. How many miners are you running?

Could also try the new compiled version of bfgminer and see if you still get the same problem.

Yes, please try this. Thanks to Luke Jr. for his very quick work.

If you are getting dropped from wifi in Linux and you're using a Raspberry Pi it is because of wireless power-saving mode. Put the line "wireless-power off" in your /etc/network/interfaces file to fix this, then either restart wireless or reboot.

Can we reflash the firmware for these units using ubuntu?

I knew how to do it before with the old Red/Blue Fury miners  Cheesy

There is no firmware to be flashed on these devices.

With cgminer, I still have the same issue of my computer getting disconnecting from the wireless network.

Yup.

Ah. Thanks for clearing that up. I was blind.  Roll Eyes

And if the red led for the core voltage is not lit, it indicates that the device is not getting enough power from usb?

Hrm... it could indicate several fault conditions. The LED is lit when the VCORE regulator thinks the VCORE voltage is being regulated within tolerances. So:

Is the miner still working? How many GH/s?

Did the VCORE LED ever light? Or is this a new fault?

Can you try it on a powered USB hub or USB3 hub?

Does it light when you plug it in and then go out when mining starts? Or does it never light?

What is your clock bits set to?

Did you do the "pencil mod"?

Do have a multimeter? Do you know how to use it?  Wink

bfgminer working fine from the last 2 hours. Hopefully this fixes my problem of internet connection. Strange!
Avg speed of 4.28 ghs each (--set bfx:osc6_bits=54) running 6 of them together on a powered hub.

Thank you for your detailed answer.

I think it was because my Anker 3.0 10 Port Hub can only handle six twin furies.
Whenever I plug in a seventh device the core voltage led wont lit while the other six are.

That's the easy answer.  Grin
