Function:
BOOL AndroidAppEventHandler_Pv1( BYTE address, USB_EVENT event, void *data, DWORD size )
Summary:
Handles events from the host stack
Description:
Handles events from the host stack
Precondition:
None
Parameters:
BYTE address - the address of the device that caused the event
USB_EVENT event - the event that occured
void* data - the data for the event
DWORD size - the size of the data in bytes
Return Values:
TRUE - the event was handled
FALSE - the event was not handled
Remarks:
This is a internal API only. This should not be called by anything other
than the USB host stack via the client driver table
