从 OpenBSD 简短的发行说明可以知道，OpenBSD 现在已经支持 USB 3.0 设备！
这个声明还表示 USB 3.0 控制器支持 USB1.x 设备，将会继续改进 USB 3.0 端口。
CVSROOT: /cvs Module name: src Changes by: mpi@cvs.openbsd.org 2014/11/07 09:44:18 Modified files: sys/arch/i386/conf: GENERIC sys/arch/amd64/conf: GENERIC Log message: Enable xhci(4). Most of the features are here, USB 1.x devices only work if they are connected to the root hub and isochronous transfers are not supported for the moment. Let me know if your controller/device do not work. In this case attach a dmesg of a kernel build with XHCI_DEBUG. ok deraadt@
