What events does it report? I'm attaching an evemu-describe event report. One possibility would be to relax the mouse button requirement from being strictly left-right-middle to just include left-right-middle, and also accept relative mouse wheels. However note that VMware's absolute usb mouse is disabled (by default) on Linux because of joydev, and even if joydev is fixed I doubt that it will be enabled by default again, as long as there are "buggy" joydevs out there. Still, I see a point in adding signature matching for it anyway, as users can override the default off setting and it would also pave the way for upcoming similar devices, as adding signature matching like this in the last minute tends to be risky... > > EV_SYN is set automatically on _every_ input device. > There is also amijoy driver that historically uses > BTN_LEFT/RIGHT/MIDDLE. > > Does the version of the patch below still work for you? > Yes, it works just fine. If there's a chance we can have that patch in 4.1GA that would be great. Thanks, Thomas
