MSC would have been a nice addition though.
I have discovered in the manual that it looks like you can enable msc in recovery mode:
RECOVERY MODE OPTIONS
No: Cancels the system recovery. Update firmware: Allows you to connect your device to a computer in order to copy the latest .AOS file (operating system) to your device and then install it. Repair System: Attempts to repair the file structure on the internal memory. This does not erase any data. No: Return to main recovery screen. Force Touchscreen Calibration: Select this, set your device down, start the calibration, and don't touch it. It will re-calibrate the screen. After the calibration is complete, select No to leave the recovery screen. Check Disk: Check and repair the system partition if damaged. Start USB MSC: Allows you to connect your device to a PC to access the internal memory. Format System: Formats the internal memory. All data (music, photos, videos, etc.), applications and settings are erased.
