If the DSL modem is not immediately recognize as an Ethernet interface when you plug it in (or when it's started an initialized and all), there's not much you will be able to do. This will probably require extra work to have a kernel driver support the modem since there is no ethernet interface exported and not serial device.

With no serial device (like ttyUSB0 or something), you won't be able to use wvdial either.

Is there any alternate option? Can i make the USB connection to be a serial type ttyUSB0? –  AndroidKid Apr 21 '11 at 4:57
    
Depends on the devices, but this one doesn't appear like it's the case. –  Mathieu Trudel-Lapierre Apr 24 '11 at 3:59
