I have a fresh 12.2 install and executing /sbin/lsusb as a non-root user yields: tuxedo(a)q25:~$ /sbin/lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 046d:08d8 Logitech, Inc.

Well, I don't have a Slackware 12.0 system lying around any more, but according to slackware.mirrors.tds.net:/pub/slackware/slackware-12.0/slackware/MANIFEST.bz2 package a/usbutils-0.72-i486-2.tgz contains /sbin/lsusb So if you don't have that package installed, Bad Things would happen. Mind you, if you are getting a status return of -1, as opposed to the shell whining "Command not found", then I'd look in the man page and see what it says. The Slack64 13.0 man page says If the specified device is not found, a non-zero exit code is returned. If you are calling /sbin/lsusb with no command-line args, that man page line is a bit vague. Hmmm... do you have something like none /proc/bus/usb usbfs devgid=83,devmode=664 0 0 in your /etc/fstab? If not, while the lsusb man page talks about /dev/bus/usb, perhaps without that line in /etc/fstab you don't get any files in /dev/bus/usb as well as not getting any entries in /proc/bus/usb. Hmmm... maybe not, I tried unmounting that and lsusb still worked. (If you don't have that mounted and want to try it without editing fstab and rebooting, run the command mount /proc/bus/usb /proc/bus/usb -t usbfs -o rw,devgid=83,devmode=664 as root.) Ummm... by any chance are you using really, really old hardware with no USB hubs? What output do you get if you say ls -l /dev/bus/sub (This works for me as an ordinary user, but you might want to try it as root on your system.) I'd be interested in knowing what happens on your system. Cheers. Jim

Simple to just change to root and back again. Is that simpler than preceding "lsusb" with "/sbin/" ? Hmmmm. > Perhaps I should have said as a user use /usr/sbin/lsusb and the > result will follow. **sigh** /usr/sbin/lsusb will work on some Linux distributions, but not on Slackware 12.2 or 13.0. Jim |
