ProcedureHow to Remove Unused USB Device Links

Use this procedure if a USB device is removed while the system is powered off. Removing the USB device while the system is powered off can leave device links for devices that do not exist.

  1. Become superuser.

  2. Close all applications that might be accessing the device.

  3. Remove the unused links for a specific USB class.

    For example:

    # devfsadm -C -c audio

    Or, just remove the dangling links:

    # devfsadm -C
