Here's the deal (I looked into this extensively last summer). HPNA version 2.0, which runs about 10Mb/s, is _not_ supported under linux- companies won't disclose info on the controller=no driver. Some HPNA 1.0 cards (1Mbps) _do_ work in linux, at least in the 2.2 series of kernels. That being said, none of these are USB, all are quite old, all are quite slow.
edit... oops- Pegasus USB to 1M HPNA are supported http://www.dce.bg/~petkan/
