+Description:
+ Writing a device ID to this file will attempt to
+ dynamically add a new device ID to a USB device driver.
+ This may allow the driver to support more hardware than
+ was included in the driver's static device ID support
+ table at compile time. The format for the device ID is:
+ idVendor idProduct bInterfaceClass.
+ The vendor ID and device ID fields are required, the
+ interface class is optional.
+ Upon successfully adding an ID, the driver will probe
+ for the device and attempt to bind to it. For example:
+ # echo "8086 10f5" > /sys/bus/usb/drivers/foo/new_id

+Description:
+ For serial USB drivers, this attribute appears under the

+ difference, all descriptions from the entry
+ "/sys/bus/usb/drivers/.../new_id" apply.
