Well, the concept is neither rare nor arguably all that broken. The paper standards floating around in the industry are so much toilet paper. The only standard that seems to really matter is what Windows has traditionally done. We may not like it, but there it is... This bites us more when it comes to the real el-cheapo stuff, notably when it comes to various USB mass storage things (which have some random USB->flash controller cobbled together by a senile llama on crack), and is almost unheard of for anythign that is "server-grade", but when it comes to no-brand random devices, it really does tend to be the case that the only testing they ever had was using Windows. And hardware is seldom any different from software: if it wasn't tested, it probably doesn't work. So it would be good if somebody knew what the Windows ID/startup sequence was/is. I think we figured it out by trial-and-error for the USB mass storage stuff. But it tends to boil down to: don't do things that aren't absolutely required (for SCSI, it was things like not asking for mode pages that weren't absolutely required, because some devices wouldn't support it, and would simply lock up if you did so!)
