It probably has nothing to do with identifying the interface. Even if
you entered the name of the interface by hand, there's a good chance
that it wouldn't allow you to capture on it.
Instead, it probably has everything to do with whether WinPcap
acknowledges the existence of the interface; Ethereal is completely
dependent on WinPcap (and the parts of the OS's networking stack that
the WinPcap driver uses, and its networking interface drivers) for
capturing on Windows, just as it's dependent on libpcap (and the OS's
packet capture mechanism, whatever parts of the networking stack the
packet capture mechanism uses, and the OS's networking interface
drivers) on UNIX, so if WinPcap/libpcap can't capture on an interface,
there's nothing Ethereal can do about it.
The change log for WinPcap:
http://netgroup-serv.polito.it/winpcap/misc/changelog.htm
says:
Version 2.3 beta, 20 sept 01
Upgrade to libpcap 0.6.2 from www.tcpdump.org
Support for Windows XP
Support for plug & play under Windows 2000 and Windows XP
The packet driver is now NDIS 5 compliant
Improved dynamic installation: WinPcap can now work on systems
without TCP/IP
Bug fixing
so if you're using WinPcap 2.2, try un-installing it, and then
installing WinPcap 2.3 beta (as the installation instructions:
http://netgroup-serv.polito.it/winpcap/install/default.htm
say, you must un-install older versions of WinPcap before installing
newer versions), and see if that helps.
If it doesn't, ask the WinPcap developers:
winpcap@xxxxxxxxxxxxxxxxxxxxxxx
about it.
