Probably not.

Programs that use libpcap/WinPcap, such as Ethereal, can capture only on
network interfaces of the sort that "ifconfig" knows about on UNIX or, I
think, that show up as network connections on Windows.

It sounds as if you're capturing on a device that's not connected to the
regular Windows networking stack, in which case you won't be able to
capture on it with any application using WinPcap.

And if it *is* a PPP device, you still might not be able to capture on
it, at least not on any flavor of Windows NT (NT 4.0, Windows 2000,
Windows XP, Windows Server):
