Comment (by bdubbs at linuxfromscratch.org):

 This ticket may belong to either BLFS or LFS depending on the final LFS
 udev rules.

 One question I'd like to dicusss is whether this is a problem at all.  The
 ticket implies that regular users should be able to list usb devices, but
 should they?  Perhaps it should be root only.  After all, the program is
 installed in /usr/sbin.

 On a related note, I'm not if its because I don't have the latest udev
 rules installed (they are about two weeks old), but when executing as
 root, I get:

 cannot open /proc/bus/usb/devices, No such file or directory

 My /proc/bus/usb directoy is empty, even though I am using a usb mouse.
