This patch-set adds the following features to dbc driver: - show the active dbc function and dbc descriptors, allowing user space to dynamically modify the descriptors. - modularize dbc core to enable it to expose different function interfaces, till now only TTY interface was exposed. - use the new framework to expose RAW interface that can be used by any user-space application to directly read from and write into dbc bulk end-points.
