some wanted to see how I wired up power supply with 10 port USB 2.0 hubs


5V 30A 150W power supply

   
connections are self explanatory  

 
Silver 10 port USB hub        


soldered power wires directly to PCB       


close up of solder connction to PCB

 
Blue (better quality) 10 port USB hub  

 
again soldered power wires directly to PCB  

 
close up again of blue USB hub 


cut outs for wires to come through hub case


if you're not comfortable with soldering then you can buy something like this above with screw terminals
below are couple links of these DC power plugs:

use wire that's heavy enough to carry power to hub to prevent high voltage drop.  eg. thick figure 8 (speaker) wire with 24 strands minimum, also known as 24/020 wire.
I used 14AWG wire which is probably over kill but I had this type of wire because I use to tinker with battery powered RC helicopters.


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.

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!

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).

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.

Tried Oscillator bits, but the only thing that changes is the temp getting higher, should it not get more speed?

thank! i will try it

Did you firmware update yet?

Still cant get mine to work properly.

In windows 7, i can get only ONE running in cgminer(various versions) no matter how i do, its always the last i plug in that gets used. Also tried plugging the USB hub in with all switched on, still only uses one.
After running for less then an hour, on Windows, the keyboard becomes unresponsible.


Havnt bin able to get Raspberry Pi with cgminer 3.10.0 to find them. Just says No Devices Detected, no matter what i do. Tried several guides for it, and a number of systems(MinePeon, RaspBian) but none of them detects it. Also tried BFGminer in minepeon, with same result.

Got a 7 port USB 2.0 hub, with external power supply, noname. The AC adapter that came with it only provided 1amp, so i made a molex cable for my computer so it would get more amps that way. Also cut the red wire in the USB, just to check if that would help, either on the raspberry, or the keyboard that becomes unrespnsible. But it didnt.

The guide i used for RaspBian Cgminer

$ sudo apt-get update
$ sudo apt-get install build-essential git pkg-config libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake
$ git clone https://github.com/ckolivas/cgminer.git
$ cd cgminer
$ ./autogen.sh
$ ./configure --enable-bitfury
$ make
$ sudo make install

Then i use ./cgminer and fill in the pool and worker specs.



Any help on this will be great, and if anyone solves this so it works, will get a reward(BTC).


Going out to buy a better hub now, to see if that helps.

I'm using the Anker 7 port as well.  LOL
Yes the firmware made a big difference. 
I will post a pic tomorrow of it running.

I was very surprised when it just ran and so well to boot after the update.

Wow that's a great speed there ManeBjorn. I might have to try the new firmwares, I am just using stock firmware right now.  I wonder if the newer firmwares would help.  I've also seen some mention of lights flashing on them but they are just solid green for me.

And I stand corrected, I received back a 7-port Anker USB 3 hub from Amazon today and they work in it.  Maybe they just don't like my 10-port Anker hubs.  They were running for a little while fine till I knocked one out trying to capture both speeds and the hub in the same picture, but I was able to hotplug it back in.

I got it fixed.
Reload the firmware.  I used the method in this thread with this tutorial.  It works perfect now at 5.7 gh/s 47 degrees C.
This site will show you how and has a great pic on how to do it.

I chose the 90 degree version and it works great.

I hope it helps.

I have not found a solution yet either.

The same happens in linux and cgminer. If i start the programme i have to unplugged and then plugged again to see it

Ok here is what is going on with my BiFury.

If I plug it in and then startup BFG or Multiminer no devices at all are found not even my existing ASIC's.

If I start the program with the BiFury not plugged in then hot plug it detects and works great in BFG miner using the manual add.
Then it runs great 5 to 5.6 gh/s.

I have looked around but I don't see any solutions.  This is the same either in my Anker hub or directly into the ports on the PC.

I am running Win7.

BFGminer is telling me COM9 does not have user privalages to install so I am not able to run my BiFury.
Does anyone no what I need to change?

Oh thats for windows, in control panel,hardware and sound,devices and printers

Is that for windows or linux? I still cant get them to run on raspberry pi. Neither with deberian or minepeon. None of them detects them

Good you fixed it. in bfgminer bat file i have -S COM4

Thanks I look forward to seeing how you did this.  I just orderd a PSU to do this as well.

Its only 40$ in europe.  But as merv77 said, the shipping cost is the same for 1 or 20 units.
