Sure. Here it is: http://people.freebsd.org/~mav/patch-zz-input-mouse9.1.7.1 It builds with our present X server, and old code even works, but I can't test the new, as even without my patch there is some problem with options parsing -- driver sees no options at all. I suppose it may be some incompatibility with our present (old) server. > And does this work on all FreeBSD versions? I believe so. libusbhid library (the only dependency) exist since FreeBSD 4.0 and I've successfully built driver with header from FreeBSD 5.1, when it got minor, but critical API change. With some luck it may even work on other BSDs as well, as our libusbhid came from NetBSD. -- Alexander Motin
