[sclug] How to find which /dev/xxx a usb device is on? (No UUID required)

[Stuart Ward]

If what you want to do is know the device name of a USB device I would
suggest you make a udev rule to map the the device name.

SUBSYSTEM=="usb", SYSFS{idProduct}=="1003", SYSFS{idVendor}=="12d1",
SYMLINK+="usbdrive"

Where the product and vendor numbers match your device and then it
will create a link to the actual device
You can also create a RUN rule to perform some action on insertion if
you want. ie mount it
