Comment 1

[John Hammink]

not sure but started seeing this in logcat:

E/slog    (   99): check_available_volume: statfs return err! [2]

Comment 2

[Jason Smith [:jsmith]]

Does this reproduce on a 1.3 Buri device?

Comment 3

[Dave Hylands [:dhylands]]

Is the internal volume in a partition of its own, and formatted using VFAT?

Comment 4

[[:fabrice] Fabrice Desré]

Looks like a yaffs2 partition:

Comment 5

[Dave Hylands [:dhylands]]

Yep:

/dev/block/mtdblock13 /mnt/internal-sdcard yaffs2 rw,nosuid,nodev,relatime 0 0

It has to be vfat for UMS to work.

Comment 6

[J Zimbrick]

This issue does not reproduce on a Buri device running the latest 1.3 build.

When USB storage is enabled and the device is plugged in to the computer via USB, the storage can be accessed and files can be added to or removed from the device.

1.3 Environmental Variables:
Device: Buri
BuildID: 20140502024001
Gaia: 667539f1ed4becc45b182a5f1046221d3eeb9e7c

Version: 28.0

Comment 7

[Jason Smith [:jsmith]]

Sounds like we either need to fix this or disable this, as right now, this doesn't work at all.

Comment 8

[James Zhang (Spreadtrum)]

I have land this patch on my side, and please help me to disable internal sdcard "Share using USB".
