# Update to get hardware ID via a string split
# Add hardware IDs to user-visible output
# Don't display IDs that are zero, since they can't be removed via this API anyway

Unfortunately, while this appears to be working to remove regular old Bluetooth devices, it apparently does not work to remove BLE devices, which was my goal.
