I am trying to get the Captive Portal working on Mac osx. When using wifi to connect to my server, I get the expected wispr request to http://www.apple.com/library/test/success.html – however, using an USB to Ethernet adapter, I only receive requests for http://init-p01st.push.apple.com/bag on my machine on the other side of the USB to Ethernet. No matter what I return or where I redirect, there is no poup automatically opening like it is for Wifi.
Is osx even capable of Captive Portal when using USB to Ethernet adapters? Or do I need a special apple adapter for that?
By the way, I already got it working on Windows machines with USB to Ethernet.

There's nothing special about "USB to Ethernet"-adapters regarding captive portals. Having a "special Apple adapter" will not help you in that regard.
You must find the error in your system somewhere else.
Actually I'm not even sure that Mac OS X looks for captive portals on wired networks. As far as I recall, the Captive Network Assistant is only activated for wireless networks. Your USB adapter would count as a wired network.
