How to get USB HID log in kernel ?

Hi All,

I am using IMX8M with yocto BSP. My kernel is providing USB HID device feature (also UAC2).

We are using libusbgx APIs in user space for configuring the kernel. And I would like to get the log (raw data in bytes ) for USB HID in KERNEL. Can someone point me to the right CONFIG in kernel ,which i need to enable or any additional log i need to add and where (file name etc.) ?

Thanks

Robin
