Was blocking those events deemed unfeasible? I certainly don't know enough about the USB CDC class to know why the spurious messages are showing up or whether they could be suppressed without a fix in the adapter firmware. But even ~30 spurious messages per second doesn't seem so bad for a multi-gig adapter that might be handling 100,000 or more packets per second. - R.
