The default.prop is set to adb only

persist.sys.usb.config=adb

It should include mass storage also like below

persist.sys.usb.config=adb,mass_storage

Need changes in the init.rc for enabling mtp, USB tethering and mass storage

Default init,rc has only adb

Need a init.rc change like what is done below

http://review.android.git.linaro.org/1573

For enabling mass storage a workaround for the time being is below:

#Associate SDcard with lun0
echo /dev/block/mmcblk1p1 > /sys/devices/platform/musb-ux500.0/musb-hdrc/gadget/lun0/file

#configuration with mass storage and adb
echo 0 > /sys/class/android_usb/android0/enable
echo adb,mass_storage > /sys/class/android_usb/android0/functions
echo 1 > /sys/class/android_usb/android0/enable

#plugin usb cable

With this the sdcard gets mounted automatically when snowball is connected to a ubuntu PC
There is currently an issue with writing to the sdcard from the PC. Further investigation needed

For snowball:

Kernel patch pushed to fix issue in write.

init.rc changes pending

init.rc changes done

http://review.android.git.linaro.org/2245

Since there is no mass storage support from UI, the below command should be used to access SD card

For 3.3 kernel
echo /dev/block/mmcblk1p1 > /sys/devices/platform/musb-ux500.0/musb-hdrc/gadget/lun0/file

For 3.4 kernel
echo /dev/block/mmcblk1p1 > /sys/devices/soc0/musb-ux500.0/musb-hdrc/gadget/lun0/file

The above command associates SDcard with lun0

On Snowball build:
https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-igloo-stable-blob/#build=339

I cannot see any USB mass storage or MTP notification on connecting USB storage device to snowball via USB hub,
Although the files on USB mass storage drive can be accesses via serial console once the partition is mounted, but form UI no USB related operations can be done.
Expected: USB mass storage or MTP notification on UI once USB mass storage device is connected.

The fix has been given for device side mass storage i.e connecting snowball to PC.

Looking at the 12.06 release build, I see:
[109464.314884] usbcore: registered new interface driver rndis_wlan
[109465.209394] scsi 7:0:0:0: Direct-Access Linux File-CD Gadget 0000 PQ: 0 ANSI: 2
[109465.211403] sd 7:0:0:0: Attached scsi generic sg1 type 0
[109465.216658] sd 7:0:0:0: [sdb] Attached SCSI removable disk

When plugging it in, but no partitions are visible from /dev/sdb, and there is no notification on the UI of the host pc. There are some notifications that pop up for usb debugging, and possibly one for usb access? on the android UI. However, since I had to unplug my mouse/keyboard to plug into the usb-otg port, I can't really get to them to check. Anyone know of a way to drive the notification acceptance from the command line? I could get to it over adb shell or serial console if so.

Hi Paul,

Please see comment #22 in this bug

You need associate SDcard to a lun thru command line.

@supriya-karanth
I tried this command For 3.4 kernel
echo /dev/block/mmcblk1p1 > /sys/devices/soc0/musb-ux500.0/musb-hdrc/gadget/lun0/file

how to access lun0 ??

Hi Amit,

Your not able to access the partition on the PC?

Did the command fail?

No the command did not failed but how to access lun0 ??

Hi Amit,

You should have been able to access lun0 in the PC. But looks like JB release has only adb and mass storage has to be enabled again

log details same as comment #9,

log shows usb storage has been attached, but flash-drive can not be mounted, can't find that USB storage in system either.

also observed with the android jb release builds:
https://android-build.linaro.org/builds/~linaro-android-member-ste/snowball-linaro-jb-13.01-release/
on the serial log it does not detect any usb flash device connected.

the same behaviour observed with snowball linaro android jb 4.2.2 builds:
https://android-build.linaro.org/builds/~linaro-android-member-ste/snowball-linaro-jb-13.02-release/
usb-mass storage device is never detected.
