[Bug 659837] [NEW] Sierra mobile bradband does not wake from usb auto-suspend

[Peter Sasi]

Public bug reported:

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.
