Hi All,

I need to switch Alcatel X602D with my linux system. The device info is:

My linux kernel and usb_modeswitch version is

Linux version 3.12-kali1-686-pae (debian-kernel@lists.debian.org) (gcc version 4.7.2 (Debian 4.7.2-5) ) #1 SMP Debian 3.12.6-2kali1 (2014-01-06)


* usb_modeswitch: handle USB devices with multiple modes
* Version 2.2.0 (C) Josua Dietze 2014
* Based on libusb1/libusbx

! PLEASE REPORT NEW CONFIGURATIONS !


I tried the configuration of the same vendor(1bbb), the log showed it finished. But in fact ,the device didn't change mode.

usb_modeswitch -v 1bbb -p 022c -c ./usb_modeswitch.d/1bbb\:f017

Could you give me some suggestion.

I attached the log I captured when using X602D under windows XP system. It switched successfully. But I can't get its switch command.

[LOM]

Section below starts with a configuration descriptor, config 1 has only one interface - the virtual cd-rom

C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=250mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
E: Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=01(O) Atr=02(Bulk) MxPS= 512 Ivl=125us

After comes another configuration , config 2 which has four interfaces

C: #Ifs= 4 Cfg#= 2 Atr=80 MxPwr=200mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=

E: Ad=04(O) Atr=02(Bulk) MxPS= 512 Ivl=125us

usb_modeswitch -v 1bbb -p 022c -u 2

should switch it over so you can access the interfaces in config 2.

Your currently active configuration is indicated by a "*" after C: in the configuration descriptor, your device/interface listing was made when the usb port was in config 1 which is the default config.

[LOM]

My post above was not of any help for you?

Hi LOM,

Sorry for no update to you these days. Because this device dailing ppp keep failed so I debug on it. And I'm not sure the configuration is OK or not.
Recent, it is proved that my ppp app issue and dail successfully.
I'm back here to update the news to you. The command "usb_modeswitch -v 1bbb -p 022c -u 2" is work!

Thank you very much.

[LOM]

Thanks Sonya, a confirmation is always appreciated even for a straightforward and simple solution.
The id will be added in next issue of usb_modeswitch data package which will be out soon.
Right Josh?

Hi,

I had switched the x602d to config #2 successfully. But gnome-ppp in Kali couldn't detect 3g modem and PPP Widget in Android 4.4.2 prints "Unknown device". What solution?
(my kernel doesn't contains /proc/bus/usb/devices)

Thx for any help.

[Josh]

The device is still fresh and not included with usb_modeswitch and PPP Widget yet. New release is imminent though.

Do I need to await the new version of PPP Widget or PPP Widget 2? thx.

Hi!

Tried Alcatel OT X602D with Fedora 22, CentOS 6.5 and Fedora 20. No luck at all.
Fedora 22 have a record for it, but end with segfault:

How can I help to locate a bug?

PS. trying to update modem firmware in case this is firmware issue.

[Josh]

There have been some fixes in the usb_modeswitch binary in the latest versions (now at 2.2.3). Try to swap your binary of 2.2.1 with the new one. You can rename the original and keep it while testing the new one; it's in /usr/sbin.

I'd guess that your problem is glibc, see if you can either update it or downgrade to 2.20

Will try on old distros and new usb_modeswitch release...
