is unused in our USB stack. Once upon a time, when I started writing the USB stack for NetBSD, there was an effort to make a standard for how USB device drivers should interact with the rest of the USB stack. This effort had contributors from just about all Un*x camps (but not Micro$oft :). I based my design on one of their early proposals since I thought it would be a good idea if we could all share device drivers with a minimum effort. Shortly after I started my work all the free Un*x people were thrown out of the USBDI work since we did not pay the USB membership fee. Well, some time has passed now and the work of the standardization group is almost public again. But alas, the new standard has grown to be a monster! I do not want to have this as the basis for the *BSD USB stack; it is far too complicated. So, since we are not even close to being compilant with the standard, I've thrown out some old baggage.
