This is what this patch does.
Take a look at this log from a little over a year ago: http://marc.theaimsgroup.com/?l=linux-usb-devel&m=113521633114762&w=2 Len Brown had a docking station with an internal hub that wasn't working right. It is device 3-5; we start trying to enumerate it at time stamp 40.129703 and give up at timestamp 103.761001. That's just ridiculous. Not to mention unfriendly, since khubd is unavailable for anything else during that time _and_ it holds the root hub's device lock, preventing many other things from working. Trying hard is fine, but to keep on trying for over 60 seconds is foolish. Alan Stern ------------------------------------------------------------------------- Take Surveys. Earn Cash.
