Qualcomm CDMA Technologies MSM (1c9e:6061) on Busybox

Post by slonik » 02 Sep 2011, 13:13

Hi,

I am new to usb_modeswitch, I'm trying to setup a busybox system that will boot up and establish a PPP over my 3G USB modem (1c9e:6061).

So my first problem is that although /sys/bus/usb/devices is correctly populated and sees the USB modem, I have nothing in /proc/bus/usb (or /dev/bus/usb but I have no udev/mdev so not surprising).

So when I strace usb_modeswitch I see it cant get the data to start its job.

Relevant part of my dmesg:

Code: Select all

usbmon: debugfs is not available

Any help would be much appreciated!

P.S when I try it on a Debian system it works fine and detects it etc

extra info: lsusb returns nothing, but the -t shows a device...

Code: Select all

[root@TESTPS]:~ # lsusb -v

OK, I solved that, needed usbfs to populate /proc/bus/usb, so just added the following to my fstab:

Code: Select all

usbfs           /proc/bus/usb   usbfs           defaults                0 0
so now I do:

Code: Select all

[root@TESTPS]:~ # mknod /dev/ttyUSB0 c 188 0
[root@TESTPS]:~ # usb_modeswitch -v 1c9e -p 6061

Looking for default devices ...

-> Run lsusb to note any changes. Bye.

[root@TESTPS]:~ # echo "1c9e 6061" >/sys/bus/usb-serial/drivers/option1/new_id
In my dmesg I then see:

Code: Select all

option 1-2:1.0: GSM modem (1-port) converter detected
usb 1-2: GSM modem (1-port) converter now attached to ttyUSB0
But then when I try to talk to the modem with nanocom at 115200, I get no response?

Thanks for any help

This should give you a hint:

Code: Select all

Warning: no switching method given.
Have a look into the config file for your device to retrieve the specific parameters.

The device is a LM003 from here:

http://www.lm-technologies.com/business ... ked_Modem/ is this a new configuration? I think they have been on the market for some time and claim to work in Ubuntu..

Thanks for any help

Can you use a more recent version of usb_modeswitch ? Like 1.1.9 ?
There were a number of fixes since 1.1.1.

So I got those few bytes from it, but it wouldn't respond to at etc..

Thanks for any more hints

If the target class is "ff", then the device is already switched to modem, either by a previous manual command (always re-plug before each manual try!) or by a hotplug mechanism (udev?) which has done the mode switch automatically right after plugging.

Don't try to switch it again.

As for the serial port, connection doesn't have to take place on ttyUSB0. There are probably other ports - you want the one using an interrupt interface. Run "lsusb -v" on the device and look for "Transfer Type Interrupt".

Thanks Josh,

Now I have traced what happens on my debian system to make ttyUSB0 work.

comparing the output of lsusb -v, on the working system I have an interrupt type interface (1 of 4):

on the non-working system I only have 1 'Bulk' interface :

    bDescriptorType         2
    wTotalLength           32
    bNumInterfaces          1
..
It seems that on the working system the "modem-manager" does some magic via plugin "Longcheer" to disconnect the one device and reconnect it making these 4 ports appear:

So how can I make this work on my busybox system (no udev only mdev), do you think it is possible?

Sorry if I'm off topic with this, if so could you direct me to a more suitable forum?

Thanks

In that case, the device has likely not switched the mode. Does it have an InterfaceClass of "8"?

BTW, the InterfaceClass "255" is the very same thing as usb_modeswitch's TargetClass "0xff" ...

I doubt that modem-manager is doing anything. Maybe usb_modeswitch is installed on that machine ?

Unfortunately, I have no experience at all with the "mdev" program you are working with. I'm sure there is some documentation out there somewhere though.
