*1 Refer to the following sections for details.
*2 X11R6.8.1/OS2 will support any type of mouse that the OS supports, 
   whether it is serial, bus mouse, or PnP type. 

3.2. BSD/OS

No testing has been done with BSD/OS.

3.3. FreeBSD

FreeBSD supports the "SysMouse" protocol which must be specified when the moused daemon is running in versions 2.2.1 or later.

When running the mouseddaemon, you must always specify the /dev/sysmouse device and the "SysMouse" protocol to the X server, regardless of the actual type of your mouse.

FreeBSD versions 2.2.6 or later include the kernel-level support for extended PS/2 mouse protocols and there is no need to specify the exact protocol name to the X server. Instead specify the "PS/2" or "Auto" protocol and the X server will automatically make use of the kernel-level support.

In fact, "Auto" protocol support is really efficient in these versions. You may always specify "Auto" to any mouse, serial, bus or PS/2, unless the mouse is an old serial model which doesn't support PnP.

FreeBSD versions 2.2.5 or earlier do not support extended PS/2 mouse protocols ("xxxPS/2"). Always specify the "PS/2" protocol for any PS/2 mouse in these versions regardless of the brand of the mouse.

FreeBSD versions 3.1 or later have support for USB mice. Specify the "Auto" protocol for the /dev/ums0 device. (If the moused daemon is running for the USB mouse, you must use /dev/sysmouse instead of /dev/ums0 as explained above.) See the ums(4) manual page for details.

3.4. FreeBSD(98)

The PS/2 mouse is not supported.

3.5. Interactive Unix

The PnP serial mouse support (the "Auto" protocol) is not supported for the moment.

The bus mouse and PS/2 mouse should be supported by using the appropriate device drivers. Use /dev/mouse for the "BusMouse" protocol and /dev/kdmouse for the "PS/2" protocol. These protocols are untested but may work. Please send success/failure reports to michael.rohleder@stadt-frankfurt.de .

3.6. Linux

All protocol types should work.

3.7. Linux/98

The PS/2 mouse is not supported.

3.8. LynxOS

The PnP serial mouse support (the "Auto" protocol) is disabled in LynxOS, because of limited TTY device driver functionality.

3.9. NetBSD

NetBSD 1.3.x and former does not support extended PS/2 mouse protocols ("xxxPS/2"). The PS/2 mouse device driver /dev/pms emulates the bus mouse. Therefore, you should always specify the "BusMouse" protocol for any PS/2 mouse regardless of the brand of the mouse.

The "wsmouse" protocol introduced in NetBSD 1.4 along with the wscons console driver is supported. You need to run binaries compiled on NetBSD 1.4 to have support for it though. Use "/dev/wsmouse0" for the device. Refer to the wsmouse(4) manual page for kernel configuration informations.

This driver also provides support for USB mices. See the ums(4) manual page for details.

3.10. NetBSD/pc98

The PS/2 mouse is not supported.

3.11. OpenBSD

The raw PS/2 mouse device driver /dev/psm0 uses the raw PS/2 mouse protocol.

OpenBSD 2.2 and earlier does not support extended PS/2 mouse protocols ("xxxPS/2") . Therefore, you should specify the "PS/2" protocol for any PS/2 mouse regardless of the brand of the mouse.

OpenBSD 2.3 and later support all extended PS/2 mouse protocols. You can select the "Auto" protocol for PnP PS/2 mice or any specific extended ("xxxPS/2") protocol for non PnP mice.

There is also a cooked PS/2 mouse device driver /dev/pms0 which emulates the bus mouse. Specify the "BusMouse" protocol for any PS/2 mouse regardless of the brand of the mouse when using this device.

XFree86 3.3.6 support USB mices on OpenBSD 2.6 and later though the generic Human Interface Device (hid) /dev/uhid*. Select the "usb" protocol and the /dev/uhid* instance corresponding to your mouse as the device name.

3.12. OS/2

X11R6.8.1/OS2 always uses the native mouse driver of the operating system and will support any type of pointer that the OS supports, whether it is serial, bus mouse, or PnP type. If the mouse works under Presentation Manager, it will also work under X11R6.8.1/OS2.

Always specify "OSMouse" as the protocol type.

3.13. SCO

The bus and PS/2 mouse are supported with the "OSMouse" protocol type.

The "OSMouse" may also be used with the serial mouse.

3.14. Solaris

Testing has been done with Solaris 2.5.1, 2.6, 7, 8, 9 and pre-release versions of Solaris 10. Logitech and Microsoft bus mice have not been tested, but might work with the /dev/logi and /dev/msm devices. Standard 2 and 3 button PS/2 mice work with the "PS/2" protocol type and the /dev/kdmouse device. USB mice work with the "VUID" protocol type and the /dev/mouse device. The PnP serial mouse support (the "Auto" protocol) has been tested and does not work. The "Auto" protocol can however detect PS/2 and USB mice correctly.

Additional USB mice can be connected using the "VUID" protocol type and the appropriate "/dev/usb/hid" device with the Option "StreamsModule" "usbms" line included in the associated "InputDevice" section.

3.15. SVR4

The bus and PS/2 mouse may be supported with the "Xqueue" protocol type.

The "Xqueue" may also be used with the serial mouse.

The PnP serial mouse support (the "Auto" protocol) is not tested.

3.16. PANIX

The PC/AT version of PANIX supports the bus and PS/2 mouse with the "Xqueue" protocol type. The PC-98 version of PANIX supports the bus mouse with the "Xqueue" protocol type.
