USB ASIC ERUPTER - Setup & Config. BCG Miner, cgminer & Hubs "Oh Pi"!

[add1ct3dd]

Here's mine up:



3 Dlink hubs - 5 erupters in each, 1 of them is daisy chained to another (raspberry pi only has 2 USB).

Running BFGMiner in Raspbian, with the Ardafruit LCD display, working perfectly.

Smart use of Fan!

Yeah, someone said the cooling wouldn't be enough, but the only thing that would be done better is a gap between the erupters - but tbh this way the air is channeled out anyway so i think its fine personally!

IF cooling is an issue you could easily update fan AND add heat sinks.
Your idea probably saves cost and electric usage of 1.1 fans per 18-21 units.
I'm also thinking a slight gap between the HUBS may be beneficial...

Yep - well I'm going to be velcroing the hubs together, so i can transport it all if need be - so maybe I just add a layer of something inbetween to seperate them out a bit!

At the moment all of the erupters are only warm to the touch, so infinitely better than no fan at all! I'll monitor it through the day

With the hubs touching the heat transferred to the hub itself builds up and does increase overall temp if just a smidge...

And a related FYI:
I recompiled current git cgminer on windows using that libusb 16rc10 I have mentioned in the cgminer thread, but on windows this time, and have had 3 AMU's in a USB3 hub on WinXP running fine for the last ... 22.5 hours

Have been watching this thread for a while and it's been really helpful!

I saw a post (that I can't seem to find.. I think on Reddit?!?!), that mentioned an alternative to MinePeon called PIckaxe.  I've used it for a few days now, and it's been extremely stable!
https://github.com/stronginthearm/PIckaxe

If you prefer Raspbian to Arch this might be an option.  I've decided to play with it, and gave it a few additions as well:
https://github.com/sephtin/PIckaxe

I'm really hoping to be able to get in touch with the author but have no idea how to contact them!  If you know stronginthearm please PM me!!

It uses BFGMiner but as soon as I find that someone has a decent grasp of how to fix the libusb problems for cgminer on Raspbian, I'll be switching it over (for my use, at least... If the dev. is ok with my working on it, I'd be happy to make it an option in the GUI...).

I fixed the libusb problems by dist-upgrading Raspbian from wheezy to jessie. Runing great.

Current README in the real cgminer also explains how to fix it.

Got my Raspberry Pi / ASMICMiner Block Erupter / DLink DUB-7 setup working.

I'll probably look into getting a newer version of cgminer working by building libusb myself but for right now this is humming along quite nicely. I'll probably buy 2 more sticks once these guys have hopefully mined a few BTC. I have no aspirations of getting a ROI, just doing this for fun.

While the sicks do get hot they don't get as hot as I thought they would. That could be because the fan is doing a great job or I haven't really run them long enough to generate much heat (<4 hours)

I've finally got my 2nd RPi and booted it up with Raspbian and built the Raspbian 3.3.4a and put it in my cgminer-binaries git
https://github.com/kanoi/cgminer-binaries
The working libusb archive is in there also for those building it themselves

So now each time I'll have both RPi_Arch and RPi_Raspbian when I build the new versions
(I missed creating the Raspbian 3.3.4a while awaiting the arrival of the 2nd RPi)

Hi guys,
with the latest version of cgminer, when i try to run my usb erupters i get che message :

" cgminer: -S: unrecognized option "

the launch string is :

cgminer -u user -p pass -o http://XXXXXXXXX  --disable-gpu --icarus-options 115200:1:1 --icarus-timing 3.0=100   -S //./COM8  -S //./COM9 -S //./COM10

Can you help me pls?

Can you help me pls?  

There is no -S option in CGMiner since, I think, 3.1.1.

Also current version of CGMiner no longer use the Serial Port Redirector software/driver.

Edit: This is all explained in the ASIC Readme.  Also check the regular readme for the --usb syntax.

Hi, i've tried to read the Guide, but when i launch the bat with :

cgminer-nogpu -u xxxx -p x -o http:/xxxxxx  --icarus-options 115200:1:1

i get an errore message : Usb Init open device failed err -12 you need to install a WinUsb driver for Amu Device 8:X (where X is one of the usb port number)

What can i do?

EDIT : Ok, i've resolved with Zadig. But how can i select the USB i want to mining?
With the command

--icarus-options 115200:1:1  --icarus-timing 3.0=100

All the USB start to work.

On the latest, you shouldn't need to specify icarus options and icarus timing as it knows the devices and has correct timings for them.

To restrict which USB devices, check the main README searching for the words "Advanced USB options:" for a comprehensive rundown.

OOOOK! I've found! Thank you !

Hi,
another little problem,
i have a DLINK 7Port (http://www.amazon.it/D-Link-DUB-H7-alimentazione-corrente-periferiche/dp/B0000B0DL7/)

With 6 USB everything works fine.
WIth 7 USB, one of them (seems sandomly) starts to give HW Error.

Any Idea?

you kidding?

if not, the D-Link 7 Port Hub has a 3A power supply. Each BE needs 0.5A.

7*0.5A = 3.5A

This is the reason for your HW errors.

[Sampey]

No i'm not kidding 
Thanks for the explanation

[stellan0r]

no problem

just touch the power supply and check it's temp - with 6 Erupters it's running pretty hot, thats why I would recommend only 5 BE's maximum for that hub. But it works stable here with 6 BE's, but I also have a fan directed at the power supply, not only at the Miners
