Hi,
I'm trying to connect the ZTE MF626 modem on the embedded linux. I have managed to switch its mode from ZeroCD to normal (modem), but the usbserial driver is not being claimed by the modem interface. Here are the steps which I am doing:
1. install usb-serial driver
Code:
root@zeus root# insmod /lib/modules/2.6.16.28-arcom2-1-zeus/kernel/drivers/usb/serial/usbserial.ko
root@zeus root# lsmod
Module Size Used by
usbserial 25392 0
...
2. plugging in modem
Code:
root@zeus root# SCSI subsystem initialized
Vendor: ZTE Model: MMC Storage Rev: 2.31
Type: Direct-Access ANSI SCSI revision: 02
sd 0:0:0:0: Attached scsi removable disk sda
3. last lines of the
dmesg output:
Code:

Accordingly to the info on the website:
http://ru.gentoo-wiki.com/wiki/MF626, interface 3 (line marked red above) should say 'Driver=usbserial_generic'.
Is there any way to force to use this driver by this interface? What else I can do to make it working?
I'm using kernel version:
root@zeus root# uname -r
2.6.16.28-arcom2-1-zeus
By the way, usb_modeswitch did not work for me ('segmentation fault' when running on the embedded system). I have followed the 'Switching off the ZeroCD' chapter on the website given above. it is in russian, but I managed to 'decode' it somehow
Some help would be VEEERRRY appreciated.
