Here is an overview of the micro-OSC device descriptor.
The VendorID/ProductID used is by permission from Microchip Technology Inc. under a sublicense agreement. This VID/PID may only be used with Microchip products.
The "Serial Number String" section of the descriptor is automatically populated with a random number, but can be changed by using the /device/id message. This data can be used to search the USB enumeration table to locate a specific micro-OSC device connected to the computer (e.g., on Mac OSX this is possible using IOKit to detect the connection of a specific USB device).
