Subject: How to skip scripts for already-claimed devices (kernel 2.4)
Date: Mon, 11 Jun 2007 02:49:05 +0000 [thread overview]
Message-ID: <200706101949.05766.embed-mobile@cox.net> (raw)
I've got an old tablet (120MHz Pentium) that I've converted for use as an
in-car navigation and music player. I'm getting hammered on startup
times because it takes so long to run the hotplug scripts. I actually
had applications run by init scripts fail because their USB devices
weren't configured yet.
I got around that by modprobe-ing drivers, but I'm still seeing delays
in "ready-to-run" of a minute or more because the system is busy running
CPU-intensive scripts for devices that are already configured.
Maybe I haven't been using the right search keywords, but I haven't
turned up any effort to speed up the usb map searches, or a way for a
script to determine that it isn't needed because the device is already
claimed by a driver. Have I missed something? Or has nothing been done
about this?
Thanks,
Ran
