btashton opened a new pull request #2383:
URL: https://github.com/apache/incubator-nuttx/pull/2383


   ## Summary
   Right now if usb tracing is enabled but verbose is disabled a debug assert 
will be triggered when ever a verbose trace point is hit because the return 
format pointer would be NULL (by design).  Instead of trying to print the NULL 
message, just return early.  This does not change any normal functionality.
   
   ## Impact
   USB tracing can be enabled in non-verbose mode with debug asserts on.
   
   ## Testing
   nucleo-h745iz:otg_fs_host with debug asserts enabled and trace on.  Prior 
this change it would hit the assert right away.
