This is version 3 of the patch, with binary data in the sysfs file instead of ASCII, as suggested by Alan Stern and Greg KH. Also now with documentation. Original Description: So I'd like to have access to the HID report descriptor in a sysfs entry, so I can read it without opening the device. hid-core seemed like the place to put it. Using the /sys/class links, for hidraw devices, this puts a new file, report_descriptor in the directory: /sys/class/hidraw/hidraw0/device/ For my USB device (for example), the new file is in: /sys/bus/usb/devices/1-5.3:1.0/0003:046D:C216.0001/ For my Bluetooth device, the new file is in: /sys/class/bluetooth/hci0/hci0:11/0005:054C:0268.0002/ I'm not super confident that these file locations are the best place, but I made a best guess so that it could be discussed. The current location is where the hid-core stuff lives. Is there a reason these directories are named bus:vendor:product:id (instead of hid-core or something similar)? Is there a better way to do this? Alan. Alan Ott (1): hid: Add HID Report Descriptor to sysfs.
