"Snowball is unable to use a USB device until it is unplugged, and plugged in again" is seemingly fixed in the 02.12 ubuntu release.

Supriya can you pls update the status?

This needs to be tested with the stable-android-ux500-3.3-1 which has fixes for USB link status issues.

We understand that patch with current kernel is not stable, hence you are waiting for 3.3-1 kernel to fix it properly.
But please attach current patch here for reference.

Supriya: Pleas attach the patch to this bug.

This bug is related to connect and boot problems in snowball and not to the SW workaround for providing vbus externally. The SW patch will be directly attached here

This needs the init script change from

#965181 next IK 3.3: Change in init scripts for latest ST-E USB driver support

Working after changes made in 965181
