They should come with a SMD Tact Switch Horizontal soldered on from the start.

Your quite correct.
I had that happen the first time I tried it as well.
Then I flashed it and it was good but a bit buggy so I flashed again and it worked great ever since.
Hopefully that can be added to the direction page for everyone.

I think there's a small but important point missing in the description of the Firmware flash process :
- you need to keep those contacts closed all the way until the System recognizes it as Storage Device, installs/initializes USB Storage driver and opens appropiate Window on the Desktop/Device Icon appears - basically until the found storage device is clearly ready to use. This will take at least several seconds.
Letting go too early or temporarily losing the short circuit (can be a bit tricky to keep it closed all the time) just for an instant won't make the LED light up again (making it look like everything works as planned) but interrupts the whole process and will cause various errors in terms of device handling.

"Have you updated the firmware?
http://c-scape.nl/bi-fury/"
I have been trying too.
Sod law, just tried it again and the storage displayed on My Computer and I updated the firmware and it works on CGminer.
you would not believe how many times I tried and it would not work.
thank you.

Hello Everyone
I need some help
I purchased 2 x Bifury miners.
Followed instruction to install them using Zadig, it installed OK, but different from the Bitfurys I have.
As you see below it shows up on my Device and Printers but does not show a Com port.
On my Device Manager the Bifury's show up on my Universal Serial Bus devices.
When I click on them and go into properties this is what is displayed.
No Com number.
I have tried CGminer with no luck (tried to run program first then plugging in the Bifury's.)
I have tried BFGminer with no luck
I normally use Multiminer with no luck.
It does not show up on any of these programs.
I have tried to update firmware, but it shows on Device and Printers as a USB host but does not show up on My Computer as a drive for me to add the firmware.
When I plug in the Bifury's the green light is always on on both.
I tried this on my laptop with same results, I am using a Ankler Hub with power supply have tired it on USB 2 and 3. No luck.
I plugged it into the USB 3 and USB 2 ports on PC, still same results.
What am I doing wrong.
Please help
Many thanks

You may need a powered USB hub like and Anker 7 port. Also are you cooling them they get quite hot and when cool they work great.
I'm using firmware 1.3 and BFG Miner 3.10.0. Sometimes when I plug in the miner, I only get hw errors (100%). I'll have to unplug it and plug it in a different port to get working. All ports on 3 computers give this problem sometimes. Anybody know why? Thanks!

Also, see how it still says No devices detected!
I think it's just a line that sticks on the top of cgminer for some reason.
I've had similar with other lines just staying permanently on top line.
Maybe ckolivas may know more why these lines are sticking on the top. not that it's any big problem, sometimes happens and sometimes doesn't.
Yes you can retry.
I had to do it to mine twice to get it to take for some reason.

hello ,
i want to upgrade the firmware from my 5ghs bi fury and do it like it is posted in the original pdf (i think i do all thinks like its showed up there)
first connectet the 2 pads,waiting 4 the green light is flashing off,erase the old firmware, put the new in (doesnt matter which firmware, ) and eject the device.
the plug off.
after that i plug in and nothing happens.cgminer doesnt accept the miners.(i do it on 2 :-/ of them ).
i was confused and thought there are damaged, and if i try to erase the firmware again, no problem , i can put it in and the removal disk opens up again , and i can do it again.....but the miners dont start again .
would be nice if any one has some tips...i dont think that im so stupid that i destroy them...i flashed several hundreds bios before and i know that it must be done very carefully.i dl them here
http://c-scape.nl/bi-fury/
its the 5ghs bifury stick.
it would benice if anyone can help:-/
thx and best regards

Here is what I am getting with mine. I might try lowering the Oscillating a bit to see if it reduces errors but this is un-overclocked.
Runs great and cool with and Artic Breeze fan on it.

Is that on windows?
This is on Win7 32bit.
It also operates the same on my Win7 64bit system.
I have not tested it on Win8 though.

Tried Oscillator bits, but the only thing that changes is the temp getting higher, should it not get more speed?
Higher values get you a higher clock rate, but also increases the hardware error rate, so higher clock settings may not result in increased overall hashing speed. The error rate is usually quite low at clock setting 54 and lower, and increases dramatically for higher settings. Of course, there's always individual variation in chips, so it's worth a try to play with this. Don't be surprised if the default setting is already optimal, though.
Thanks.

Bought a new USB 2.0 hub with a 3.5 amp ac adapter.
Updatede the firmware on both, via this guide http://c-scape.nl/bi-fury/ chose the 90 degree version.
Kind of the same problem on windows. Except this time, one of them is unknown device. They both work fine alone, with a higher speed then before 5gh/s+, but it will still only run one.
And the problem hasnt changede at all in linux, dosnt find any of them, no matter what hub, or how i hotplug them.
Also noticed that the LED's on the pens behave different now. Before the green led was always on, when the device was plugged in. Now when you start it, the red led turns on, then off. And when the pen is in use the green led flashes.

have you tried this method.... (I'm using Windows 7)
First plug the Bi-Fury into a USB port and look in 'Devices & Printers' in the control panel to see if Bi-Fury is there. If not download 'zadig.exe', run it and select in 'Options' menu to 'show all devices', then select the Bi-Fury in the drop down list and select 'WinUSB' driver and click install.
Then re-check 'Devices & Printers' in the control panel to see if the Bi-Fury has come up, if not reboot PC and check again. When the Bi-Fury is visible in the 'Devices & Printers' in the control panel then unplug it from USB port and run 'cgminer' with you pool settings and replug (hot plug) the Bi-Fury's one by one (not to quick, let it start hashing and then plug another).
Yeh sorry about not mentioning it earlier, did the zadig thing yesterday, after reading through some forums for a solution.
Used zadig_v2.0.1.162.exe and added winusb driver to them.
After my last post, i got them both to run on Windows 7, without my keyboard being rejected. So either the bigger AC adapter, or firmware helped.
The next problem is to get it running on my Raspberry Pi, since the computer i use for Bi*Fury, as of now, is also my scrypt mining rig. And it has some restarts....
Also, see how it still says No devices detected!
I think it's just a line that sticks on the top of cgminer for some reason.
I've had similar with other lines just staying permanently on top line.
Maybe ckolivas may know more why these lines are sticking on the top. not that it's any big problem, sometimes happens and sometimes doesn't.
try hitting 'd' for [D]isplay options and then 'z' for [Z]ero statistics to see if clears it.
the keyboard is unusable again, using on-screen keyboard untill i find a solution for raspberry.
and yes, D then Z cleared it.

Thanks that looks much easier than I was worried it would be.
Great job.

some wanted to see how I wired up power supply with 10 port USB 2.0 hubs
5V 30A 150W power supply

again soldered power wires directly to PCB
close up again of blue USB hub
cut outs for wires to come through hub case

cut red power wire in USB cable that connects from USB hub to PC USB port.
this is to prevent PC USB port trying to power anything connected to USB hub (power isn't required as your using power supply for power)
here's a thread where there's good info on USB hub, etc.. https://bitcointalksearch.org/topic/which-usb-hub-to-use-with-block-erupters-nanofury-nf1-bpmc-red-fury-ant-u1-253749
Note. if you're going to do similar with a USB 3.0 hubs they may be powered with 12V instead of 5V, the same applies but 12V power supply required.
Very nice!
Found out I need something like this for
powering hex•fury also:)
And if you remove the polyfuse in the blue hub
(that green thingy), you don't need to cut the
red wire.
