I recommend you install it on 6-stable, because on 7-current it needs > some small patches to compile, due to some changes in the kernel API lately. Yes, I suspect the probe order is significant, but the only system I use USB devices on is my laptop and I really don't want to roll it back to stable. I can continue to work around it until you have a set of current patches for me to try. I'm really anxious to try out the new stack as I am hoping it will make USB behave better in terma of power management on my laptop. That's why i don't build USB into my kernel, but just load it when I need it. I don't normally read usb@, so I may drop you a note in a couple of weeks to see if the stack has been updated for current. Thanks! -- R.
