Hi, yes: use of gnome-ppp/wvdial instead of modemmanager (i.e. disable mobile broadband on networkmanager applet). With a direct dialer and correct ttyUSB port, the modem's response is immediate as the LED changes from red to flashing green. Anyway it seems already fixed in later versions -correct me if I'm wrong- (I'm still using 11.04, I usually update once a year). Regards.
