USB_ModeSwitch

Hello everybody!

I'm Cesar from Brazil. First of all I would like to congratulate you and the others that make this amazing project to be a useful tool!

This is my first post on this forum.

I've got an Olivetti 155 USB modem, and it doesn't work with the last version of usb-modeswitch (1.1.7).

I would like to improve usb-modeswitch, adding support for this modem, if no one already did.

Do you have any tips of how can what's going on with the modem when I run usb-modeswitch?

Some useful information:

when I run lsusb, I got:

$lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 04f2:b107 Chicony Electronics Co., Ltd CNF7070 Webcam
Bus 001 Device 023: ID 0b3c:c004 Olivetti Techcenter (*** Here is the modem ***)
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


For my first test, I added the following lines to the file /etc/udev/rules.d/40-usb_modeswitch.rules

# Olivetti Olicard 155
ATTRS{idVendor}=="0b3c", ATTRS{idProduct}=="c004", RUN+="usb_modeswitch '%b/%k'"


When I plug the modem, it begins flashing the yellow light (that's a good thing), but then it comes back to the flashing green light, and this is the storage mode. No /dev/ttyS* is created.

On this linux, I use an ZTE MF-100, and this one works just fine.

I attached the kernel log output when I plug the modem on my machine.

By the way, I'm using one customized LinuxFromScratch, with almost all new packages, all of them build from the source.

Thank you,

Cesar

There is probably a misunderstanding; your device did in fact switch, but the target product ID is yet unknown to the existing config file.

This is where you plug in:And this is after switching: The only thing you have to do is adding your target ID (c004) to the existing config file "0b3c:f000".

Delete the line "TargetProduct= 0xc003" and instead add this: This should result in giving you the "option" driver, bound to the device after switching and providing the ttyUSBx ports.

Thanks for your help! With your tips, I could see the /dev/ttyUSBx.

I'm sorry for misunderstood the usb-modeswitch configuration. But I could only get the /dev/ttyUSB{0-5} only after loading the usbserial kernel module by hand, with the following command:

modprobe usbserial vendor=0x0b3c product=0xc004

I could solve this creating the file /etc/udev/rules.d/14-olicardmodules.rules with this content:

SYSFS{idVendor}=="0b3c",SYSFS{idProduct}=="c004",RUN+="/sbin/modprobe usbserial vendor=0x0b3c product=0xc004"
KERNEL=="ttyUSB[23]",ACTION=="add",SYSFS{idVendor}=="0b3c",SYSFS{idProduct}=="c004",RUN+="/bin/sleep 2"


I don't know if this is the best way of making the module to be loaded automatically.

I discovered that /dev/ttyUSB3 is the serial device that work as a modem. But I couldn't connect to the internet with this modem. After setting /etc/wvdial.conf, when I start the wvdial command, it starts dialing, it connects and lauch the pppd command. After that, the pppd dies with this message:


pppd[5186]: pppd 2.4.5 started by root, uid 0
pppd[5186]: Using interface ppp0
pppd[5186]: Connect: ppp0 <--> /dev/ttyUSB3
pppd[5186]: LCP: timeout sending Config-Requests
pppd[5186]: Connection terminated.
pppd[5186]: Modem hangup
pppd[5186]: Exit.

After that the modem dies, It doesn't answer for any command, even the "ATZ".

I tried to use the modules usb_wwan and option, but it dosn't make any difference.

I know that my problem is out of the scope of this forum.

Thanks for the fast feedback.

You should not have to load any driver manually with usb_modeswitch installed. Otherwise, please enable logging in "/etc/usb_modeswitch.conf" (see main doc page, paragraph "Troubleshooting").

Post the resulting log after replugging (might take some moments to appear).

Sorry for taking too long to answer... I was too busy this week...

I've enabled the log at /etc/usb_modeswitch.conf with the EnableLogging=1 option.

Doing this, the file /var/log/usb_modeswitch_1-1\:1.0 was created when I plugged the modem at the USB port.

Here goes the file content:

I could see the udev doesn't know the device.
I'm sorry because I didn't had time to study the documentation properly... Maybe this weekend...

If someone can help, it would be nice.

Thanks

It's as I said in my first reply (see above):

The target product ID "c004" must be added to the config file. It's there after switching but not recognized.

You have to edit the config file "0b3c:f000" and make the changes I described.
