Re: Alcatel x060s - incorrect port

[Andrey Alakozov <aa29ww gmail com>]

Hi,

In udevadm DB, ttyUSB1 has ID_MM_LONGCHEER_PORT_TYPE_AUX=1 flag, and
ttyUSB2 has ID_MM_LONGCHEER_PORT_TYPE_MODEM=1 flag.

I've changed ATTRS{idProduct}=="0000", ENV{.MM_USBIFNUM}=="03"

in 77-mm-longcheer-port-types.rules to be both aux and modem
and it worked! Now NM could connect OK.

While playing with it I found that NM fails to find modem if Ethernet 
connection is active:

# tail -f /var/log/syslog

...
Apr 29 13:18:07 andrey-laptop NetworkManager: Could not get modem 
driver: Did not receive a reply. Possible causes include: the remote 
application did not send a reply, the message bus security policy 
blocked the reply, the reply timeout expired, or the network connection 
was broken.


If I detach Ethernet before plugging modem in everything works fine.
It's a minor issue for me because I do not intend to use Ethernet and 3G 
connections simultaneously.

See udevadm output below.


# udevadm info --export-db
