Wie ging es weiter? Läuft alles? Welche Software hast du jetzt auf dem Pi und nach welchem Guide (wenn überhaupt) bist du vorgegangen?

Have you thought to try minepeon.
very simple setup..

Is there any progress to make this idea working?
Yes! Monday yxt will ship my block erupters
Okay, great! Please keep us informed. I would like to do similar setup, but not sure about Dlink DUB-H7 hubs - they have 3A power supply, so it will be able to feed only 6 Erupters, 7th will be underpowered, I think. But anyway, let us know!

From D-Link: http://www.dlink.com/us/en/home-solutions/connect/usb/dub-h7-7-port-usb-2-0-hub
And:
So, 7*0.5A= 3.5A = 143%

Connectivity Rules:
Up to five cascaded hubs
Maximum cable length between each hub: 5m
Up to 127 devices

Supplied Charging Current:
Standard Mode:
All seven USB ports- 0.5 A per port 2
2 Enter the Fast-Charge Mode by disconnecting the DUB-H7 from your computer, or by powering off your computer. It is recommended that the total power consumption of the connected USB devices should not exceed 2.4 A, or 12 W.

1. The Dlink DUB-H7 delivers 3 amps according to specs I found online. I'm not sure that will power 7 Erupters as they need 500 milliamps each.
2. I read somewhere the Pi starts having trouble handling Erupters at around 50. Not sure if this is still a valid issue or not. But if so, you might want to split your 49 Erupters between 2 Pis just in case?

For me, it should work only if all the hubs are powered. The USB port on the RPi aren't giving a lot of power.
Of course! Also the main hub is powered.
So no problem to realize a daisy chain like this with raspberry pi?
In Raspbian (The s.o. of the pi) i'll set any particulary setting?

You are under the 127 "devices" limitation of USB, so, yeah, it should work.
Now, I don't have any of these Block Erupter, so I don't know how to setup it with CGMiner:

extra noch zu der Filiale gefahren, da Briefe dort um ~17.15 abgeholt werden.
Pakete offensichtlich (zumindest heute) früher. Aber Vorfreude ist ja bekanntlich die schönste Freude.
-----------------------
Linux users should not need any help.
So here for the win users only:
happy hashing
But be careful! they get hot during operation!
I recommend cooling. Direct some airflow over the heat sink.

So here for the win users only:
- download
latestcgminer-3.1.1 :
http://ck.kolivas.org/apps/cgminer/ - install this driver:
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
no reboot required - plug in the usb miner, wait few seconds
- search in the Device Manager for:
Silicon Labs CP210x USB to UART Bridge (COMx)
keep the COM number(s) in mind - start cgminer with the following arguments:
cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COMx
for more than one device: cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COMx -S //./COMy
happy hashing

Hi,
First of all, sorry for my bad english but i'm italian.
I would realize something like this with raspberry pi and 49 USB block erupter:
But i'm not sure that all is compatible and that'll work when i'll setup the system.
For get the reward, you must be very complete in the reply, (very like detailed explication about critical step in the setup of the rig)
When all the hardware is installed and work i'll send the btc.
