From my understanding the device indicated by you is a wifi card with an ethernet interface. It shouldn't be only an adaptor (something like: input ethernet, output USB) since it can connect to a wifi router, so it is very similar to a wifi USB external device.
Why there are the model name and VendorID:ProductID ? Can't you find the device using lspci or lsusb?
About the ethernet interface: you are right, I have to add it for wifi card as soon as possible
About Debian: Debian is not fully free, so we can't allow users to test their devices with it. You can use a Trisquel live cd for the test. Would it be possible for you?
Thanks!
