1AdbTest is a sample program that implements a subset of the adb USB protocol. 2Currently it only implements the "adb logcat" command and displays the log 3output in a text view and only allows connecting to one device at a time. 4However the support classes are structured in a way that would allow 5connecting to multiple devices and running multiple adb commands simultaneously. 6 7This program serves as an example of the following USB host features: 8 9- Matching devices based on interface class, subclass and protocol (see device_filter.xml) 10 11- Asynchronous IO on bulk endpoints
