I have seen with BSP39 that the contents of a folder are not correctly displayed when connected to a PC via the Media interface (which is default) i.e. some files are missing. The same folder viewed on the device via File Explorer or on a PC via ADB correctly shows all the files. Disconnecting and reconnecting the TC55 does not resolve this issue- it requires a reboot in order to correctly show all the files. Please see the attached screenshots for an example.

  My preference would be for the TC55 to operate as a USB memory stick when connected to the PC - is this planned to be added to the KitKat OS version so that it works the same way as the TC70/75?
