Laserhorse,
Can a backup pool be put in the .conf? I added a pool while mining and hit 'S' and 'W' but it didn't change anything. What about other options can be added, like difficulty?

yup - add'l pools can be added to the conf file like so:

Code:

"pools" : [
   {
   "url" : "FIRST POOL ADDRESS:PORT",
   "user" : "WORKER NAME",
   "pass" : "PASSWORD"
   },
   {
   "url" : "SECOND POOL ADDRESS:PORT",
   "user" : "WORKER NAME",
   "pass" : "PASSWORD"
   },
]

And yes - you can add a pool or make other changes from within cgminer:
hit "S" to go to settings,
then "W" to write the config file
and save it by entering the following location: "/home/pi/cgminer.conf"
and enter "y" confirm that you wish to overwrite the preexisting file.

Thanks for the great project, LaserHorse.

My Pi Miner has been running great for the past week with 9 Erupters. But, I'm having a problem adding more Erupters to it and hope that someone may be able to share some guidance.

When trying to add 6 additional Erupters (for a total of 15), I discovered that it will only "see" 13 total. i.e., typing "ls /dev/*USB*" only lists ttyUSB0 - ttyUSB12, even though there are 15 Erupters installed.

A few notes:

I built a second RPi Miner, with a newly imaged SD-card, and ran into the exact same issue.
The 15 Erupters were installed across 3 DLink DUB-H7 hubs, 5 in each hub. So I don't think its power related.
These 3 hubs feed into a 4th hub which is connected to the RPi.
I'm using Raspbian, and followed the build process specified in your project walk-through.
The 2 Erupters that it wont see are running fine on a separate RPi miner. So it doesn't appear to be a hardware problem with those Erupters.

Any recommendations for troubleshooting this? Is there a default max number of USB serial devices that are enumerated in Raspbian?

hmm so the hubs are *not* connected in a series/chain, correct?
I haven't tested with more than six erupters myself, so you have me at a bit of a loss here.
Shot in the dark, but have you tried specifying ttyUSB13 & ttyUSB14 even though they don't show with ls?
