bash: determinare il path di una periferica usb

ecco un piccolo script bash per determinare il path dev di una periferica usb (ad es: /dev/ttyUSB0)

#!/bin/bash

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

ecco un esempio di output

/dev/video0 - SuYin_HD_Video_WebCam_CN1014-S36D-OV05R-VA-R03.01.01
/dev/input/event7 - SuYin_HD_Video_WebCam_CN1014-S36D-OV05R-VA-R03.01.01
/dev/input/mouse0 - Logitech_USB_Optical_Mouse
/dev/input/event5 - Logitech_USB_Optical_Mouse
