Hi Remi, it looks like you are trying to use the user space driver (the one from http://speedtouch.sourceforge.net/), but have the kernel driver loaded (the speedtch module; see http://www.linux-usb.org/SpeedTouch/). These two drivers do not play nicely together. > The firmware is loaded and the modem is initialized correctly using the > following command : > > /usr/local/bin/modem_run -v 1 -d /proc/bus/usb/001/002 -f > /usr/local/bin/mgmt.o -s -m You can use modem_run with the kernel driver, but you need to add -k to the switches you pass to it. > Gotcha, I found your ADSL ALCATEL SpeedTouch USB modem! > best offset 6463 with probability 87% > best offset 532634 with probability 100% > BLOCK1 : 991 bytes uploaded : OK > BLOCK2 : 511 bytes downloaded : OK > BLOCK3 : 526187 bytes uploaded : OK > BLOCK4 : 511 bytes downloaded : OK > Reference : 3EC 18607CDAA 02(see under your modem box) > ADSL line is blocked? > ADSL line is synchronising > ADSL line is synchronising > ADSL line is up, downstream at 608 kbit/s, upstream at 160 kbit/s > ADSL link goes UP > > Then, I'm using the following command : > > pppd call adsl The ppp config file for the kernel mode and user mode drivers differ.

Yup. > Does anyone has an idea about what is wrong in my configuration? > What modules are necessary (ppp-async, n_hdlc, speedtch)? > May be something is missing in my modprobe.conf or .config file? Both drivers work fine. You just need to decide which one you want!
