We have  a custom board based on imx6ul. Currently we have two OTG ports. One OTG2 port we are using for Host devics. OTG1 for downloading kernel(mfgtool). We are trying to use OTG1 as device. Like connecting/read/write from PC to imx6 vice versa. What is the procedure or which driver needs to be enabled. 

Below is the kernel log.....By this log I come to know that usb device driver is already registered. How to coomunicate with PC??
