I have used following
Projects/NUCLEO-H563ZI/Applications/USB_Device/CDC_Standalone/USB_Device library.
for STM32U575 Series controller (USB OTG FS) which is easily enumerated and running data at 1 mbps speed with good stability.
But same library I used for "NUCLEO-U5A5", (USB OTG HS) , configured clock and PHY for OTG HS - which is getting enumerated successfully also but not stable , and sometimes getting disconnected and PCD_IRQ is not triggering sometimes.
Is OTG_HS has something different or missing something or core difference , when compared to OTG_FS used in stm32u575 ? kindly guide.
