hi friends When i try to configure,,usb modem via ppp0 after everything while i give command it says unrecognized option /dev/ttyUSB0 if any body has done networking via usb modem please tell me..
I am using a huawei usb dongle (ec1260) no issues. Set it up using the instructions posted at http://doc.slitaz.org/en:guides:dialup. My modem defaulted to ttyUSB2 (although when you look at dmesg, it shows ttyUSB0 to ...4 as connected).
Not sure if this will help, but this is how I got my device working
First install a package called usbutils. Then in terminal type lsusb It will bring up something like this: brenton@trixarian:~$ lsusb Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 1d09:4000 TechFaith Wireless Technology Limited Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Note that my device ID number is 1d09:4000 - this will be different for you, but the process is the same.
Now go to Control Box , go to the initialization tab, make sure option is in the load module box, if not, add it. Mine looks like this: option snd_als4000 (snd_als4000 being my sound card).
Click the Add Local Commands button and add: echo '1d09 4000' > /sys/bus/usb-serial/drivers/option1/new_id Note the numbers, my device's ID number is 1d09:4000, so I added '1d09 4000' above - change these numbers to your device's ID number (remember to exclude the : from the lsusb readout!). Save the file and open a terminal.
In the terminal type: modprobe -v option echo '1d09 4000' > /sys/bus/usb-serial/drivers/option1/new_id and your device should be working - yet again change the ID number to your devices number.
