I don't get stuck there, but the changes Bitmain have made to CGminer break something that adafruits scripts reply on. Guess we will just have to wait until the drivers are merged back into the main Git of CGminer
That could be the api change they made. They pissed kanoi off when they changed the hashrate from MHS to GHS. I changed it back on my branch. Try it and see if it works with your adafruits scripts. It did get miner.php to work properly when there were both old and new miners in the config.
It built and ran perfectly for me just now (no more fiddling around with the driver! Yay!!!), but the Adafruit display is still stuck on the IP address unfortunately...
