Hello. I'm trying to work with my Huawei e173s-6 via serial port. The modem is unlocked. I've installed usb_modeswitch, changed config to

Code:

# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# Evaluated by the wrapper script /usr/sbin/usb_modeswitch_dispatcher
#
# To enable an option, set it to "1", "yes" or "true" (case doesn't matter)
# Everything else counts as "disable"


# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0

# Disable check for MBIM module presence and configuration globally (to aid
# special embedded environments). Available as per-device parameter
# 'NoMBIMCheck'

DisableMBIMGlobal=0

# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_<interface-name>" and probably others

EnableLogging=1

# Optional increase of "delay_use" for the usb-storage driver; there are hints
# that a recent kernel default change to 1 sec. may lead to problems, particu-
# larly with USB 3.0 ports. Set this to at least 3 (seconds) in that case.
# Does nothing if the current system value is same or higher

#SetStorageDelay=4

# If the configuration for your Huawei modem uses the standard switching method,
# you can globally set an alternative method here which provides a different mode:
# either plain serial PPP (for older modems) or NCM which integrates nicely
# with recent Linux distributions, possibly avoiding configuration through a
# modem built-in web page. All other modems are not affected.
# Available as per-device parameter 'AltHuaweiMode'

HuaweiAltModeGlobal=1


When I plug in the modem, lsusb shows the following:

Code:

Bus 003 Device 019: ID 12d1:1001 Huawei Technologies Co., Ltd. E161/E169/E620/E800 HSDPA Modem


Seems like everything ok, but no any /dev/ttyUSB* in /dev directory.

I've tried to do that

Code:

# modprobe usbserial
# modprobe -v usbserial vendor=0x12d1 product=0x1001


but there is no effect. Does somebody know how to get it work with serial?

Thank you in advance

g-virus,

usbserial is a parent to lots of lower level things.
Code:
<M>   USB driver for GSM and CDMA modems
looks like a good choice.

If that's not enough put your entire kernel .config file onto pastebin site please.

I'm sorry I didn't answer a long time. Yes, it works with this module! Thank you for the idea. I didn't try to look for some modules missing because I forgot that my usb-serial converter uses different module. Now I can see three ttyUSB0-1-2 in /dev directory, so it works, thank you again
