Hello, I would like to ask a question about the U-Boot USB enumeration of STM32MP157:
Using a custom board with the STM32MP157 (FUSB302MPX), openSTlinux6.6,:

Problem description:
Through "STM32_Programmer_CLI -c port=usb1 -d ../../FIP_artifacts/arm-trusted-firmware/tf-a-stm32mp157d-develop_mp157-mx-optee-programmer-usb.stm32 0x1 -s 0x1 -d ../../FIP_artifacts/fip/fip-stm32mp157d-develop_mp157-mx-optee-programmer-usb.bin 0x3 -s 0x3"
Write to the board memory, PC side
"Error: Unable to reconnect the target device: time out expired, Error: Start operation failed"

On the board: Repeat log "dwc2_ep0_setup: bRequestType = 0x80(IN), bRequest = 0x6 wLength = 0xff, wValue = 0x302, wIndex= 0x409"
