void configureDevice ( void   ) [inherited]

In USBDevice.cpp > USBDevice::requestSetConfiguration, configureDevice() is called after realiseEndpoint() (in USBCallback_setConfiguration()). So we have the following USB buffer management policy: 1. Allocate for CEP on connect(). 2. Allocate for EPX in realiseEndpoint(). 3. Deallocate all except for CEP in unconfigureDevice().
