I'll have to scan the emails in my queue to see what the issue is (umm, is this really 300+ messages in just the last couple days??) but my initial reaction is to avoid complications. We have enough configuration knobs ... but userspace hasn't even begun to use them. Adding more knobs will not improve that situation at all. At one level, we want USB mice and keyboards to act pretty much like the PS2 variety. Which means being wakeup sources in most cases ... though BIOS settings often overrides the PS2 stuff. It'd make sense that _removing_ devices not normally be a wake event for USB ports. But we don't always have that option... - Dave
