thanks for prompt reply,

TU_ATTR_WEAK bool tud_msc_is_writable_cb(uint8_t lun) is now added to mcusb.cpp and write_protect is working .............

  1. when right click, delete option is not coming
  2. format of the drive is not allowed, message pop up indicating write protected
  3. when paste is done, its trying to copy and after long time prompt message of write protected is coming.

Thanks again .....
