I've done everything from http://en.gentoo-wiki.com/wiki/Huawei_E173 guide to get my E173 modem working, but after plugging it in it does not start modem. Dmesg says only about storage device:
Code:
usb 1-1: new high speed USB device number 7 using ehci_hcd
usb 1-1: New USB device found, idVendor=12d1, idProduct=1446
usb 1-1: New USB device strings: Mfr=3, Product=2, SerialNumber=0
usb 1-1: Product: HUAWEI Mobile
usb 1-1: Manufacturer: HUAWEI Technology
scsi8 : usb-storage 1-1:1.0
scsi9 : usb-storage 1-1:1.1
scsi 8:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 2
scsi 9:0:0:0: Direct-Access     HUAWEI   SD Storage       2.31 PQ: 0 ANSI: 2
sd 9:0:0:0: Attached scsi generic sg1 type 0
sr0: scsi-1 drive
sr 8:0:0:0: Attached scsi CD-ROM sr0
sr 8:0:0:0: Attached scsi generic sg2 type 5
sd 9:0:0:0: [sdb] Attached SCSI removable disk


After that there is no any ttyUSB device in /dev.
Of course I have sys-apps/usb_modeswitch installed.
Here's my kernel config http://bpaste.net/show/38440/

p04ty,

Have you run sys-apps/usb_modeswitch?
emerge it if required, my stick works without it.

Check you are actually running the kernel you think you are too.
The data/time in
Code:
uname -a
is the build date of the running kernel.

Have you loaded the option module with
Code:
modprobe option

p04ty,


CONFIG_USB_NET_CDCETHER is missing from your kernel.

Thx for the tip, you were right. That option was missing in my kernel, now it works.

Enabling CONFIG_USB_NET_CDCETHER was the solution for me as well!
Thank you!

PS:
I know this is an old thread, but...
@NeedySeagoon: How did you figure that out?!
