tty-to-usb-device

find out the usb device path for a usb serial tty ex (/dev/ttyACM0)

lets say you have an arduino or some usb serial connected. this will find the path to the usb device it belongs to. im usaing it for the module reset-usb to kick unresponsive devices. might only work on linux but should work on anything with /dev /sys and probably udev for uevent files

var lookup = require('tty-to-usb'); 

lookup('/dev/ttyACM1',function(err,device,meta){
  console.log(err,device,meta)
});

output will be something like this.

false '/dev/bus/usb/002/017' { link: '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/tty/ttyACM1',
