I got my Lancelots, assembled a stack of four of them, git pulled the latest cgminer, but cgminer does not seem able to handle four of them.
I tried switching the fourth one I had turned on with another in case it was a bad board, but it just cannot seem to handle four boards period.
It even gets segfaults, no hardware should be able to segfault the mining program, it has to be something broken with the software.
To compile it with icarus support I had to install libusb-devel, that didn't suffice so also had to install libusb1-devel.
It detects four boards, but then claims they are all zombies and invents another four, claims they are all zombies, invents yet another four and so on, in /tmp it has 90 or more imagined devices from constantly inventing more of them.
So I tried BFGminer. It is even worse, it cannot get anywhere with them, at least with cgminer I had occassionally gotten as many as three of them to work.
I tried starting a second copy of cgminer to try to use just the fourth board, but it basically seemed to be claiming all USB devices were in use or something.
Even only running three it still had problems, else maybe by now I would be setting up four computers to run three boards each.
I am using Fedora Core 17, 64 bit.
The USB cables are plugged into a "USB-HUB 113" 13 ports USB 2.0 hub from NewEgg.
I am now starting to clutch at straws, like wondering how to detect whether the USB port the hub is plugged into on the computer is USB 2.0 or higher or lower...
This is with four boards switched on:
