Hi, all. I managed to connect fine using a Motorola c350 cellular phone, connected to the PC with a mini usb cable, and I'm reporting below the procedure I followed. Now I want to do the same with another cellular phone, the Nokia 6630, to get faster. I followed the same procedure but couldn't establish connection. Any idea about why the same procedure works fine with Motorola c350 and doesn't work with Nokia 6630, and how to fix that? I configured the phone also, according to what the provider indicated.
Any help highly appreciated, happy christmas holidays, thanks in advance, Rodolfo %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Debian Sarge 3.1, kernel 2.6 I connected the phone to the PC with a mini usb cable, then did: # dmesg |fgrep acm but got no output. Then I did: # modprobe cdc-acm , then again # dmesg |fgrep acm and got the following output: drivers/usb/class/cdc-acm.c: Ignoring extra header cdc_acm 1-2:1.8: ttyACM0: USB ACM device usbcore: registered new driver cdc_acm drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters drivers/usb/class/cdc-acm.c: Ignoring extra header cdc_acm 1-2:1.8: ttyACM0: USB ACM device drivers/usb/class/cdc-acm.c: Ignoring extra header cdc_acm 1-2:1.8: ttyACM0: USB ACM device . The device '/dev/usb/ttyACM0' was not there. I created it with: # mknod /dev/usb/ttyACM0 c 166 0 .

At the end of each file I left a blank line. I connected the phone to the computer and started the connection with: # pon gprs_vodafone and closed it with: # poff gprs_vodafone . In the file '/var/log/pppd.log' are the reports.
