Mass storage doesn't seem to work

[bcaller]

On Ubuntu I get the mass storage device to appear and I can change files, but when I eject it the app doesn't close automatically. When I eventually have to reset the badge the storage is corrupted and I need to factory reset.

Also saw some weird things like Sorry, could not display all the contents of “2821-0000”: Error when getting information for file '/media/ben/2821-0000/ screen.app': Input/output error

Or for file /media.../ import os which makes it seem like something pythony is going wrong.

I am also unable to get the Mass Storage App to see that Ubuntu has unmounted. No unmounted messages via the serial terminal either.

Maybe we need to add a button "I have already unmounted, please close anyway". @drrk, any thoughts?

Having same issue on MacBook and OS X.
Either Eject or unmount from command line does not terminate app. reset on badge causes corruption and factory reset.

And observed in Windows 7

I've fixed it again in MacOS, but Linux and windows needs more investigation.

Hi @drrk where is the tilda library so that I can see how the methods storage_enable_usb() and storage_disable_usb() work?

Here is the mass storage code:
