Maybe it's running in "Home PNA" mode by default, so the connector (identical to an ethernet connector) isn't talking ethernet? Personally, I think the bul transfers have to happen over the other interface. I've seen this once before, a while ago. If there's a Linux driver that works, maybe you can crib from it, where the documentation is fuzzy? It also occurs to me that you might try it under Windows, if you have a recording USB monitor, and see what's different between your usage and Windows. One particularly nasty thing might be it needing a firmware download from the driver (it's possible). Doug Ambrisko could probably help you out; I remember he did a driver for a similar USB dongle (two interfaces) at Whistle. -- Terry
