Have you tried:
The board you cite is not supported, so not surprising it ain't working ;-)
Which variant did you start with ?

I'm try directly connect 5V to PA9, not happening too. What can be wrong?

No, but I'll try. On the board STM32L476RE, respectively, for compilation i use variant "Dragonfly" USB circuitry differs only in the absence of VBUS and ID lines
Tried this settings and nothing has changed:
define STM32L4_CONFIG_LSECLK 0 // 32768
define STM32L4_CONFIG_HSECLK 0 // 16000000
define STM32L4_CONFIG_SYSOPT 0 // SYSTEM_OPTION_VBAT_CHARGING
define STM32L4_CONFIG_USB_VBUS GPIO_PIN_NONE // GPIO_PIN_PA9
Added a pull-up resistor to the USB_DP line as well as on boards with STM32F103 and it worked! =))
You need to keep STM32L4_CONFIG_LSECLK 32768

I'm known, already keep it and creat separate board variant with pin names
Right, but there is no external pullup required. If so, something else is badly wrong. STM32L476 has a builtin pullup.
