Title: Fix/usbmsd report error no sdcard

This tells the host that no disk is available when the SDCard fails initialisation (ie not present or broken).

Only tested against linux so far, please report results with various versions of windows and OSX.

Desired behaviour : usb resets are NOT issued when the SDCard is absent.
