Yes. You'll need to write code that implements a virtual com port on the USB. It is considerably more complicated than UART. Here is one example.

Why would you even need to confirm this, don't the specification say it supports USB?

Writing application code might be more challenging.

YES, As USB VCP or MSC Device would have examples
