Hello, I am trying to connect my 5 erupters to my pi to start mining.
I bought a usb hub from ebay, and a 3500mA 5v power supply to ensure power is not an issue.
I follow the instructions on
http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/install-cgminerbut when I connect the first erupter the hub "dissappears" from the pi:
pi@bomberb17 ~ $ lsusb
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0951:1625 Kingston Technology DataTraveler 101 II
Bus 001 Device 005: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB
Bus 001 Device 006: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB
***(I connect the first erupter to the hub)***
pi@bomberb17 ~ $ lsusb
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0951:1625 Kingston Technology DataTraveler 101 II
pi@bomberb17 ~ $ ls /dev/*USB*
ls: cannot access /dev/*USB*: No such file
Power is definetely not an issue, I also tried cutting the red wire on the cable that connects the pi and the hub to ensure the pi is not getting backpower.
