Hi Again, I just found out that hid.h and usb.h are not present in /usr/include/linux/ though they are present in /usr/src/include/linux/. Does it mean that user mode programs (such as 'usb.c') cannot use hid.h? If so, is there any other header that user mode programs can use to get HID class specific structures/functions?
