https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221074 --- Comment #13 from Dexuan Cui <decui@microsoft.com> --- (In reply to Dwerva from comment #12) Hi Dwerva, maybe you can use a Generation-1 FreeBSD VM as a workaround? Mou= se works with Gen1 FreeBSD VMs, because Hyper-V emulates a legacy mouse. For Gen-2 VMs, Hyper-V doesn't emulate the legacy mouse, so we have to deve= lop a para-virtualized front-end mouse driver in the VM to use mouse. For Linux= VM, the driver is https://github.com/torvalds/linux/blob/master/drivers/hid/hid-hyperv.c. I o= nce tried to port the driver to FreeBSD, but unluckily it turned out I couldn't understand how the mouse APIs work in FreeBSD (I studied the mouse APIs for= a few days but still didn't quite understand which sets of API should be used= and how the Hyper-V mouse events should be converted to the mouse events that c= an be understood by FreeBSD) so I gave up... :-( I hope somebody with more knowledge on FreeBSD mouse APIs can help. --=20 You are receiving this mail because: You are the assignee for the bug.=
