Dear Sirs, I want to tell you a true story about one windows user who is not like the others.
F4t discovered that his FR panics when he tries to connect it to his windows box. Asked on -cdevel and was told that it's not reproducible by others so he needs to investigate it himself. For that he needed to somehow save kernel oops message and he was told to recompile a kernel with lindi's ramconsole patch. Surprisingly, instead of endless moaning, tales about unfairness in life and other unrelated talks he did just what was required (guided by lindi, of course). With his kernel messages it was trivial to understand the source of a problem, so i prepared a quick hack to workaround it and F4t confirmed rndis networking now works with his windows xp sp2 (?). Crude patch attached but i very much hope that someone other who understands rndis better than me will come with a real solution soon. Other than that i suggest those unfortunate windows users to install the latest service pack. A good hint from upstream developer is at [1]. [1] http://lists.zerezo.com/linux-kernel/msg19822805.html
