I'm working on a USB CDC project to get a virtual com port using an STM32L476VG processor, I have it configured to be a device only in hopes to simply pass information over the com port between my board and PC. I am able to trigger the interrupt when the USB connection is made, but I am not able to have the computer identify the USB. I set everything up in the STM32Cube application and have the latest virtual com port drivers installed from ST. I was able to run essentially the same USB style on an STM32L476G-EVAL board, both projects configured the exact same in everything with regards to the USB. Are there any suggestions on how to handle the Unrecognized USB for my main board I plan to be using? I've already confirmed the interrupt occurs and that I have the correct drivers installed, I'm just not seeing it be recognized correctly.
