Public bug reported:

version: 3rd(2015 version) on Trusty(14.04)

It suspends and resumes successfully at the first time, then WWAN
devices disappear and fails to suspend.

workaround 0:
BIOS, Always On USB to disable, USB 3.0 mode to enable

workaround 1:
disable cdc* modules in rootfs and initramfs(you will lose WWAN feature)

workaround 2:
reset that WWAN device from xHCI(USB 3.0) port to EHCI(USB 2.0)

We still need a fix.
