Original issue's description:
> Convert device::UsbConfigDescriptor and friends to structs.
>
> These classes do not need to be classes and expecially don't need to be
> abstract classes as this leads to a complicated implementation and
> complicated tests. All USB devices no matter the platform will have the
> same descriptor data.
>
> This change follows the model of device::HidDeviceInfo.
