After check, it is not U-Boot issue, it is imx_usb should update to support new u-boot-dtb.img.

With your patch, file u-boot-dtb.img
u-boot-dtb.img: u-boot legacy uImage, U-Boot 2019.04-00664-gdbe9a81ff0\270, Firmware/ARM,
Firmware Image (Not compressed), 490914 bytes, Thu Apr 25 07:26:46 2019, Load Address:
0x17800000, Entry Point: 0x00000000, Header CRC: 0xCBE07038, Data CRC: 0x2C710405

without your patch, file u-boot-dtb.img
u-boot-dtb.img: Device Tree Blob version 17, size=1399, boot CPU=0, string block size=139, DT
structure block size=1204

Actually now u-boot-dtb.img is a FIT image with a device tree wrapper. So need fix imx_usb
to support both legacy and new image format.

Peng.
