求助，关于STM32U5的HIGH SPEED USB时钟源的问题求解

如题，STM32U595，USB要使用HIGH SPEED，也就是480M总线速度，手册上说的HS必须要用HSE做时钟源，但是现在试了下，用HSI做时钟源，也是可以的，这是个例还是确实可以用HSI做时钟源？如果批量出产品，用HSI做USB HS时钟源，会不会经常故障，良品率不高？
USB on-the-go high-speed (OTG_HS)The devices embed an USB OTG high-speed device/host/OTG peripheral with integratedtransceivers. The OTG_HS peripheral is compliant with the USB 2.0 specification and withthe OTG 2.0 specification. It has software-configurable endpoint setting and supportssuspend/resume.This interface requires a precise 60 MHz clock that is generated from the internalUSB PHY PLL (the clock source must use a HSE crystal oscillator).
