Hi Jean, I hope you're doing well!
Unfortunately, there are no plans for a CMSIS-driver USB driver distributed by us on the SDK package.
The SDK package contains a USB driver and accompanying USB stack for use of the USB module included in this MCU family. More information about the SDK package for the LPC55S69 can be found in its download page in the MCUXpresso SDK builder, here.
I apologize for the inconvenience this may cause.
Best regards,
Sebastián
