Installation of ubuDSL fails.. My System just hangs after installation. Restarting solves the issue. But UbuDSL is not installed. Any work around for this?? I need configure this usb device as an Ethernet device(eth1) in networks. how do i set this? I pls help..

Answer 1

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.
