I have a feeling that KPPP is "abandonware" these days. I used it for a 
usb-modem in 9.10 with success. In 10.04 the modem did not work at all, 
some kind of kernel issue. In 10.10 it works fine again but only with 
wvdial. KPPP can not see the port /dev/ttyUSB0, have no idea why

have you tried using networkmanager? It works for one of my modems 
(CDMA) but not another that is GSM.

kind regards,
