How do you think about a wording variant like the following?

   Change description:
   A SuperSpeed device shall include the USB 2.0 extension descriptor
   and shall support Link Power Management when operating in USB 2.0
   High Speed mode. (See also: USB 3.2 specification 9.6.2.1)
   But we do not support it generally. Thus disable this functionality
   by default.
   Otherwise, the device will enter LPM suspend mode when connected
   to Win10 system.


Would you like to add the tag “Fixes” to the commit message?
