Hello,

I'm trying to detect my phone modem (Reliance - rconnect) on my SuSe 10.0 os (for accessing internet).

The phone model is LG LSI 110. It is a fixed wireless phone that has an in-built modem.

On Windows XP, the internet works just fine.

This phone is connected to my laptop using a USB cable.

However, on installing the rconnect software on linux, the device is not listed in /dev.

The rconnect.conf file needs an entry of the /dev/*xyz* which points to my phone.

Funnily, when I look into hardware info - the USB section list my LG CDMA WLL phone with device name as /dev/ttyACM0. But this name '/dev/ttyACM0' does not exists in /dev list!

I would like to create this device listing using mknod command. But then, how do I know the "major & minor" number of this device?? I've checked Hardware Info, /proc, /sys to get these details for the usb device - but to vain.

Thanks

major is 166
minor is 0

google for /dev/ttyACM0 to find more info !

Hey Thanks! for that info

Google has thrown up a lot of posts relating to /dev/ttyACM0.

I'm sure..will find a lot more useful information.

Thanks again!

I have much the same problem with a ZTE fixed wireless phone. It works when using Suse 9 LiveCd, but not in any other linux flavor. I'm guessing that the kernel doesn't have the correct modules loaded. I know cdc-acm is the important one, with ftdi-sio, usbserial and either uhci or ohci (posibly both) also needed - but there must be more cause it doesn't exist in /dev as you said. Someone out there, please give a full list of modules required!

I am using a Palm Treo 700p and have been working on connecting Linux to the internet using this phone. It has an internal modem that works fine under windoze, but the ttyUSB0 modem interface on Linux would crash the phone. Then I found a program, mobile-stream.com/usbmodem.html, that used the ttyACM0 interface. My problem was when I plugged in the phone all I got was the ttyUSB* devices. Doing links and mknod commands don't work, because the ttyUSB* device is through the "usbserial" module, not the "cdc-acm" module. Even when the cdc-acm module was loaded, the usbserial connected with the phone first. I found that I had to rmmod the usbserial module, and load cdc-acm first, and then when I plugged in the phone it created the ttyACM0 device.
