HID: export headers properly

2008-04-22T09:34:59+00:00

I have people whining about using these headers in userspace, and they have __KERNEL__ markings which implies they're supposed to be exported. I also added the required linux/types.h include to hidraw.h since it uses the __u## kernel types.

HID: fix HIDIOCGRDESC memory access in hidraw

2007-10-15T15:12:00+00:00

Fix bogus copying of data into userspace when HIDIOCGRDESC is issued. HID-transport layer makes sure that dev->hid->rdesc is not larger than HID_MAX_DESCRIPTOR_SIZE. Noticed-by: Al Viro Signed-off-by: Jiri Kosina Signed-off-by: Linus Torvalds

HID: add hidraw interface

2007-10-14T12:47:26+00:00

hidraw is an interface that is going to obsolete hiddev one day. Many userland applications are using libusb instead of using kernel-provided hiddev interface. This is caused by various reasons - the HID parser in kernel doesn't handle all the HID hardware on the planet properly, some devices might require its own specific quirks/drivers, etc. hiddev interface tries to do its best to parse all the received reports properly, and presents only parsed usages into userspace. This is however often not enough, and that's the reason why many userland applications just don't use hiddev at all, and rather use libusb to read raw USB events and process them on their own. Another drawback of hiddev is that it is USB-specific. hidraw interface provides userspace readers with really raw HID reports, no matter what the low-level transport layer is (USB/BT), and gives the userland applications all the freedom to process the HID reports in a way they wish to.
