 SUPPORTED DEVICES
 
-Currently supported devices include the Avalon (including BitBurner), the
-Butterfly Labs SC range of devices, the ASICMINER block erupters and the BPMC
-BF1 (bitfury) USB devices. No COM ports on windows or TTY devices will be used
-by cgminer as it communicates directly with them via USB so it is normal for
-them to not exist or be disconnected when cgminer is running.
