The issue with locating the expected interface and endpoint descriptors
arises because `configDesc` (USB_CONFIG_DESCRIPTOR) and `IfDesc`
(USB_INTERFACE_DESCRIPTOR) are incremented by structure size rather than
by actual descriptor length.
Specifically:
- `configDesc` should be incremented by its actual length.
- `IfDesc` should be incremented by its actual length.
This incorrect increment causes misalignment, preventing access to the
subsequent interface and endpoint descriptors.
[Suggested Solution]
Update the code to increment the pointers by the actual descriptor lengths,
ensuring proper access to all descriptors in the USB configuration.
