i've been trying for a couple of days to get the speedtouch 330 dsl modem to run under linux and finally i got successful

so here it is

1. get the firmware from thomson's website
   
2. using the firmware_extractor split the firmware you got into speedtch-1.bin and speedtch-2.bin and move those files into /lib/firmware or wherever your distro wants it (i use FC3)
   
3. setup the dsl connection and if in FC3 forget the gui it sucks when it comes to dsl
   

create /etc/ppp/peers/adsl

lock
ipparam "adsl"
defaultroute
noipdefault
usepeerdns
noauth
holdoff 4
maxfail 25
persist
asyncmap 0
user "xxxxx"
name "xxxxx"
plugin /usr/lib/pppd/2.4.2/pppoatm.so
8.35

create /etc/ppp/chap-secrets

"fti/xxxxx" "*" "votrepasswd" "*"

create /etc/sysconfig/network-scripts/ifcfg-adsl

PEERDNS=yes

create the startup script adsl.sh

/sbin/modprobe pppoatm
/usr/sbin/pppd call adsl

and so it worked

note that if there is a pap-secrets file login will fail, if after the modem is pluged in the usb and the two leds are not blinking while the phone line is not pluged then the modem is not initialized and maybe you have the wrong firmware or it is in the wrong location or maybe you need the modem_run package but i think it is in the distro

good luck . . .
