+This is a test app for the USB accessory APIs. It consists of two parts:
+
+AccessoryChat - A Java app with a chat-like UI that sends and receives strings
+ via the UsbAccessory class.
+
+accessorychat - A C command-line program that communicates with AccessoryChat.
+ This program behaves as if it were a USB accessory.
+ It builds both for the host (Linux PC) and as an android
+ command line program, which will work if run as root on an
+ android device with USB host support
