Assuming you have a supported usb interface, being uhci, ehci, or ohci, and a usb hid mouse with or without a scroll wheel, this guide may or may not help you.
Although most people report that their USB devices, including HID mice work out of the box on 5.x, I still recommend that you recompile your kernel to make sure everything works properly.
If you are still using a legacy release of FreeBSD you must recompile your kernel for USB mouse support.
Assuming you are using the x86 architecture, a standard chipset such as Sis, Via, or Intel, and have a USB 1.1-2 compliant host adapter, you first need to do the following:
# cd /usr/src/sys/i386/conf # cp GENERIC HOSTNAME # nano -w HOSTNAME
Make sure the following entries are present under the USB support portion of the configuration file:
/usr/src/sys/i386/conf/HOSTNAME # USB support device uhci # UHCI PCI->USB interface device ohci # OHCI PCI->USB interface device ehci # EHCI PCI->USB interface (USB 2.0) device usb # USB Bus (required) device ugen # Generic device uhid # "Human Interface Devices" device ukbd # Keyboard device ums # Mouse
Comment out the ehci entry if your motherboard doesn’t have a USB 2.0 compatible interface. Comment out the ukbd entry if you don’t want support for usb keyboards. Save the configuration file.
# /usr/sbin/config HOSTNAME # cd ../compile/HOSTNAME # make depend # make # make install # reboot
Assuming you didn’t disable the mouse daemon, once the system has booted, you should see a mouse pointer on the console which should be movable.
In order to setup xorg/x11 with your usb mouse, you should disable and kill the mouse daemon. Edit /etc/rc.conf and add the following lines to the bottom:
In the /etc/X11/xorg.conf or /etc/X11/XF86Config file, under the InputDevice section, the following should be used if you have a usb mouse with a wheel.
Identifier "Mouse1" Driver "mouse" Option "Protocol" "Auto" Option "Device" "/dev/ums0" Option "ZAxisMapping" "4 5"
You now have a working usb mouse on your FreeBSD workstation. Congratulations!
