The pamphlet is incorrect. One USB 3.2 Gen 1 Type-C port
The (8 page) manual (shipped along with computer) says regarding the front port that it is USB 3.2 Gen 2 Type-C. However, the PDF document describes it as 3.2 Gen-1 Type-C. And the other port next to it (left as you look at it)  as USB 3.2 Gen-1. The USB port for the Type-C is much smaller and different shape than standard USB.
