# Change the name of the usb id to a "more" human redable format.

# - $env{ID_PATH} usually is a name like: "pci-0000:00:10.0-usb-0:2.3.3.4:1.0-port0" so we strip the "pci-*"
#   portion and only use the usb part
# - Transform the USB "speech" to the tree like structure so we start with "usb0" as root-complex 0.
#   (tr -d -) does the replacement
# - Replace the first group after ":" to represent the bus relation (sed -e 0,/:/s//b/) indicated by "b"
# - Replace the next group after ":" to represent the port relation (sed -e 0,/:/s//p/) indicated by "p"
