Hi zhangzhiyong
just for test one can try to re-connect the usb cable to see if
mass storage device appears. Try to test mass storage test using linux and imx-test (../mxc_usb_test)
imx-test
www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.7.tar.gz
Check with oscilloscope signals USB_OTG_ID,USB_OTG_VBUS,VDDUSB
and compare its wavefroms with good board.
Best regards
igor
