Hi All, I'm modifying USB MSD driver for a custom device (UASP). USB Core would know the details of the device inserted if it is a normal Mass Storage Device or UASP based on certain descriptors. I would like to pass on this info to MSD driver. The MSD driver has two parameters as inputs of type struct usb_device_id and struct usb_interface. My question is: Can i modify these data structures by adding additional fields. Will this impact other USB drivers? or is there any better way to communicate this info to MSD driver? Thanks in Advance.
