HI Mikhail Modin 

For LPC54xxx, we only have USB demo code enclosed in MCUXpresso SDK.

https://mcuxpresso.nxp.com/en/builder 

By default that USB demo code is for FS USB0. If you need HS USB1, you need enable high speed mode with below code:

/*! @brief LPC USB IP3511 FS instance count */
#define USB_DEVICE_CONFIG_LPCIP3511FS (0U)

/*! @brief LPC USB IP3511 HS instance count */
#define USB_DEVICE_CONFIG_LPCIP3511HS (1U)

rebuild project. 

Make sure you have external power supply to the board when use HS USB.

Have a nice day.
