I am trying to use USB HID on STM32L452RE with Windows. I am getting the error that "Device Descriptor Request Failed". Note that I am able to successfully use the USB CDC on this device so I do not think it is a hardware issue.

I have followed the instructions from he STM32 instructional -> https://www.youtube.com/watch?v=3JGRt3BFYrM

Any ideas what is wrong or how I can debug/narrow down the issue?
