I'm trying to make a script that takes the product and vendor id printed by using lsusb, then checking against this ID to find the USB device's directory in /sys/bus/usb/devices.
I initially thought the Bus and Device number printed by lsusb would point to the appropriate folder. For example, if Bus = 002 and Device = 002, the USB's directory would be /usb/devices/2-2. Unfortunately, this turned out to not be the case.
I can manually find the appropriate folder using this command I found in another thread:
for X in /sys/bus/usb/devices/*; do
echo "$X"
cat "$X/idVendor" 2>/dev/null
cat "$X/idProduct" 2>/dev/null
echo
done
However, I need a script that can automate finding this folder.
If I understood your question, the following script should do the job:
#!/bin/bash
if [ $# -ne 2 ];then
echo "Usage: `basename $0` idVendor idProduct"
exit 1
fi
for X in /sys/bus/usb/devices/*; do
if [ "$1" == "$(cat "$X/idVendor" 2>/dev/null)" -a "$2" == "$(cat "$X/idProduct" 2>/dev/null)" ]
then
echo "$X"
fi
done
