Title:
  Sierra mobile bradband does not wake from usb auto-suspend

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I am using NetworkManager (and ModemManager under it) in 10.10
  Maverick (the issue was also present on 10.04 Lucid as well, before I
  upgraded) on my Lenovo Thinkpad T61, kernel 2.6.35-22-generic.

  I started setting power/level to auto using udev for power saving due
  to usb auto suspend.

  Connecting to moble broadband fails if /sys/bus/usb/devices/6-1/power/level contains auto and the device has suspended.
  It succeeds, if it is set to on.

  I can connect with power/level set to auto only if I am fast enough
  and Disable then Enable Mobile Broadband in NetworkManager in quick
  succession, before the device has time to suspend.

  Seems like NetworkManager / Kernel cannot get sierra module out of
  suspend using ttyUSBx.

  Logs according to NetworkManager / ModemManager bug reporting protocol
  are also attached.
