Looking at
http://cgit.freedesktop.org/ModemManager/ModemManager/tree/plugins/telit/mm-plugin-telit.c?id=1.4.12
seems like the Telit plugin only handles tty port, but I am using QMI
with the Telit LE910. Should it still be using the Telit plugin?
The following lines appear at the log (in this order):
(Telit) [wwan0] filtered by subsystem
(Telit) [ttyUSB4] filtered by udev tags
(Telit) [ttyUSB1] filtered by udev tags
(Telit) [ttyUSB2] filtered by udev tags
(Telit) [ttyUSB3] filtered by udev tags
(Telit) [ttyUSB0] filtered by udev tags
(Telit) [cdc-wdm0] filtered by subsystem
I think at least one of the ttyUSBn device nodes should NOT filter
Telit plugin, right? From the code:
/* If we didn't match any udev tag: unsupported */
if (!self->priv->udev_tags[i]) {
mm_dbg ("(%s) [%s] filtered by udev tags",
self->priv->name,
g_udev_device_get_name (port));
return TRUE;
}
I have been looking at
http://cgit.freedesktop.org/ModemManager/ModemManager/commit/?h=mm-1-4&id=0505021ac6c79c28bd28184a9daa988b0712c71f
and seems like the idProduct is not in the udev rules. Should the
idProduct 1201 be added? Looking around (for exapmle
http://www.spinics.net/lists/linux-usb/msg115457.html) seems like this
is the right productId for Telit LE910.
I attach all the relevant information (I think) for the modem.
