Enumerate USB devices with udevadm

There's a lot of ways to find USB information, but they seem to give too much or too little information. This script from http://unix.stackexchange.com/questions/144029/command-to-determine-ports-of-a-device-like-dev-ttyusb0 is perfect for me:

for sysdevpath in $(find /sys/bus/usb/devices/usb*/ -name dev); do
    (
        syspath="${sysdevpath%/dev}"
        devname="$(udevadm info -q name -p $syspath)"
        [[ "$devname" == "bus/"* ]] && continue
        eval "$(udevadm info -q property --export -p $syspath)"
        [[ -z "$ID_SERIAL" ]] && continue
        echo "/dev/$devname - $ID_SERIAL"
    )
done

Running it on my system gives:

~ $ usbdiscover.sh

/dev/video0 - Chicony_USB2.0_HD_UVC_WebCam
