This seems to be a reasonable description to me.

Consider that a by-product of unmapping the device.

Do you mean violating the ASIO interface standard? Or wave out, Direct Sound or WASAPI? J. River s/w is probably not communicating directly with the USB protocol stack in Windows or to a USB device.

Interfaces are rarely so well specified that no unexpected quirks show up when real entities communicate using that interface. The early quirks become part of the real-world interface. Later devices just have to fit with the quirks exhibited by the pioneer devices.

Maybe some time with a USB analyzer will be needed too. As I said in the other post, don't assume that something works until you have tested it.
