Hi I just rolled my own 2.6.17-rt4 (I'm now running 2.6.15) and upon boot it seems that usb was "not working". My usb mouse sisn't work, neither did my usb soundcard or my usb midi keyboard. I seem to remember something about udev, but before I start messing with my system, I'd appreciate if someone could confirm that this this coould in fact be the cause of the problem. If so; how reversible is the process of installing udev, I seem to remember something going... not so well some time back when last tried to go back from udev. If not; what else could be the problem? Surely someone else must have had this problem... I'm running debian/stable and I simply took my trusty 2.6.15 config and copied it to /use/src/linux (symlinked to actual kernel tree) and ran gconfig + save before making the kernel. Thanks in advance for any advice. -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions
