Hi,

I'm running in Centos 7 with Mobily Quanta 1K3M Device

This is the log of Quanta 0408:ea25 when run usb_modeswitch:

GNU nano 2.3.1 File: usb_modeswitch_1-1.3

The error reported by libusb is probably not a real error, which usb id does lsusb show for the device after "switching failure"?

Modeswitch can change device ID to 0408:ea26, but the usb is still storage.

Not the same storage device as in 0408:ea25 which created a sr device ie a virtual cd-rom.
0408:ea26 created a sd device ie a disk device which is for the TF/SD card in the dongle.

Why did you cut the log at that point?
There should be both a serial usb driver binding and a net usb driver binding creating linux ttyUSB devices and a linux net device.
Your log should show that.

Hi LOM

There is no more log for serial binding or net usb binding and no ttyUSB device.
These are all the lines of log for switch.

Which command can I show you more?

If you don't see a driver binding to the modem after the switch, then there is
  1. either the "option" driver module missing on your system
  2. or the "option" module is there but the kernel is so old that the USB ID of your modem is not yet built into it
The second possibility means that the driver does not 'know' your modem and does not bind to it automatically.

You can check this by loading and binding that module manually (as root or with sudo):

Code: Select all

# modprobe -v option
# echo "0408 ea26" > /sys/bus/usb-serial/drivers/option1/new_id
Then look at the output of "dmesg" again.

Looking at the linux drivers I see that there is no support for Quanta 1K3M yet so adding temporarily support for it by echoing the device id to the new_id function as Josh suggested will get part of the dongle working.
It is not a good longtime solution though and it will only give you a serial ppp dialup ttyUSB linux device and not a high speed net device.
Are you able to edit the source for two linux drivers and compile them afterwards?
If so, are you also willing to send in patches to the linux driver maintainers so the dongle gets linux support?
