I have a couple of scripts that automount USB devices under mdev. See https://wiki.gentoo.org/wiki/Mdev for the general setup, and https://wiki.gentoo.org/wiki/Mdev/Automount_USB and https://wiki.gentoo.org/wiki/Mdev/Automount_USB/automount Once set up, "it just works". If you want to go spelunking through /sys for connected USB devices, here are a few hints. I currently have connected to my machine... * a Dell keyboard * a Logitech trackball mouse * an external USB hard drive * 2 USB keys The output below shows that not every USB device has a serial number, and the "Patriot Memory" key has a serial number but no manufacturer...
