Windows thinks that this is a new Normal or Composite device.  The device is effectively changed to a new Configuration.

This gets around the problems that Complex devices usually have, at a cost of perhaps 30 seconds of time that the PC host will need to re-enumerate the device. This process is triggered in the software of the peripheral device. Depending on how you write that software, it could happen in response to some special command from your PC side program, or from some adjustment (like a button press) made to the peripheral device.

A Soft Detach device designed in HIDmaker FS can have two (2) Configurations, each with up to three (3) Interfaces.
