Like several people on this list, I have been getting annoying messages at boot 
time about nonexistent storage devices on empty usb ports. An earlier post by 
Bruce Dubbs suggested a simple edit of /lib/udev/rules.d/50-udev-default.rules 
to prevent this. On my LFS7.6 system with systemd, this edit worked very well.

However on LFS7.7 with sysvinit, it does not work. Not only do the messages 
remain, but the change somehow screws up xorg's evdev driver so that neither 
the mouse nor the keyboard work any more. This means that not only can I not 
use X but I can't even get back to a console to correct the problem!

At first I thought I might have made a typo during the edit, so I tried again 
by copying the previously edited file from LFS7.6 (where it works perfectly 
well) to LFS7.7. It turns out the effect is real, though it only shows up after 
rebooting with the modified file; simply shutting down and restarting X under 
the new rules doesn't cause problems.

A diff run shows that the only difference between the old and the new files is 
the position of the line
ACTION!="add", GOTO="default_permissions_end".

Can anyone explain this?
