229 Get the parameters for the USB mass storage media.
231 This function get the parameters for the USB mass storage media,
232 It is used both to initialize the media during the Start() phase
233 of Driver Binding Protocol and to re-initialize it when the media is
234 changed. Althought the RemoveableMedia is unlikely to change,
235 it is also included here.
