Hello,
I have trouble with my new mobilcom debitel stick,
the "XS Stick W14" by 4g-systems. It works fine under Windows, but I can't make it to switch after plugging it in. Curiously, the modem *is* detected if the stick is already inserted while booting, but that seems not to be related to usb_modeswitch (see below).

I'm using ubuntu 09.10, Kernel 2.6.31-14-generic on a Lifebook, and
# /etc/usb_modeswitch.conf contains:

Code: Select all

DefaultVendor=  0x1c9e 
DefaultProduct= 0xf000
TargetVendor=   0x1c9e
TargetProduct=  0x9603

...which should be ok according to this post

after plugging in the stick,

Stick inserted while booting

Curiously, the modem *is* detected if the stick is already inserted while booting. This works only when /etc/modules contains:
usbserial vendor=0x1c9e product=0x9603

Then I can see
> ls /dev/ttyU*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2

and I can access the modem via /dev/ttyUSB1. However, I still cannot get connected, and to work this out it would be very helpful to be able to unplug and replug the thing...

Here is more data for the case of successful detection:

[valyR]

see the ADU topic - maybe you should remove too the file

modem-modeswitch

in mandriva is located in /lib/udev

[hornsby]

maybe you should remove too the file
modem-modeswitch

Hi valyR,
I removed /lib/ubev/modem-modeswitch, but the behavior is unchanged (after booting)...
cheers, hornsby.

It's strange to have "usbfs" bound to a storage device as a driver.

Do you have an "usb-storage" module in your system?

Can you post a "lsusb -v -d 1c9e:" after plugging in, without any switching attempts ?

DeviceClass should be 8 or 0, the first InterfaceClass should be 8.

[hornsby]

Here's the data..

prior to plugging in:

> lsmod|grep usb
usbserial 36232 0
btusb 11856 2
usbhid 38208 0

after plugging in, w/o switching attempt:

> lsmod|grep usb
usb_storage 52544 0
usbserial 36232 0
btusb 11856 2
usbhid 38208 0

I don't know where this usb_storage comes from after plugging in, but I found
> grep usb_storage /lib/modules/2.6.31-14-generic/*|wc
346 1040 35286

[Josh]

Hmm, looks O.K.

And storage is activated too.

What does "dmesg" say about the storage device? Any errors after plugging? Or is it bound correctly and made available as a "/dev/sd*" device?

[hornsby]

Ok, this is now solved.

I made a "complete removal" of the debian package usb-modeswitch, which I had installed earlier. Now it switches as it should under version 1.0.5

Previously I had just executed ./usb_modeswitch-1.0.5/usb_modeswitch
with the older package still installed, and there must have been some bad interference (which I really don't understand).

For reference, here again my usb_modeswitch.conf:

Code: Select all

# /etc/usb_modeswitch.conf
# for  "XS Stick W14" by 4g-systems 
DefaultVendor=  0x1c9e 
DefaultProduct= 0xf000
TargetVendor=   0x1c9e
TargetProduct=  0x9603
MessageContent="55534243123456788000000080000606f50402527000000000000000000000"

I get /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3

NetworkManager does not work (yet), but I can connect using wvdial. The crucial point is not to use /dev/ttyUSB1 as suggested by wvdialconf, but to use /dev/ttyUSB2.

Josh,
thanks a lot for your help and for this great program!
