The only reasonable explanation for this is that the products array
passed to dev_findproduct was corrupted - it appears to have faulted
on the products[n] lookup on line 93.
However at least on casual inspection I don't see how
usbd_fill_deviceinfo gets to dev_findproduct or what that ?() is;
maybe someone else can take it form here...
