[PATCH 1/1] Ubuntu: SAUCE: Workaround for SATA drive failure on Ubuntu installation

[Bryan Wu]

From: Dinh Nguyen <r00091 at freescale.com>

BugLink: http://bugs.launchpad.net/bugs/431963

Original patch was from Dinh Nguyen. That one find the root cause
of this SATA drive failure issue. The USB2SATA chip GL830 can not
accept the ATA PASS THROUGH command.

This patch will skip the ATA PASS THROUGH command only for GL830
USB device. So it will not effect other USB devices.
