I need that file to build userspace apps using hidraw.
linux/hidraw.h has never been installed please e-mail linux-kernel@vger.kernel.org and linux-input@vger.kernel.org to see if that's what they want to do
It is a new API just merged into kernel 2.6.24 (it will replace hiddev). There are clear indications in it that it should be included in userspace headers and other distributions (Fedora rawhide and debian experimental at least) include it in their header package.
that doesnt preclude checking with upstream and/or sending them a patch ... hidraw.h also needs hid.h
2.6.25 will be released shortly and my patch should be part of that
