Install new device on Freebsd

 Basically, the standard FreeBSD installation media contain almost all the drivers that you need. A notable exception is the graphics driver, as SirDice has mentioned above, you’ll need to install that package. Then Xorg should run almost exactly the same as you’re used to on Linux.

• pciconf -lv lists all PCI devices, whether FreeBSD has a driver for it or not. If you see something like noneX@pciX:… at the beginning of a line, then no driver is attached to this device.
• usbconfig lists all USB devices that are currently attached (whether supported by a specific driver or not). This includes the internal “root hubs”, so don’t be surprised if the list is longer than expected.
• dmesg can be used to review the kernel’s boot messages. Use dmesg -a to include other output that has been printed to the system console. Note that the dmesg buffer is circular, so it is overwritten after a while, and the oldest entries get lost. In this case you can look at the file /var/run/dmesg.boot that contains a snapshot of the buffer right after the boot process has finished.
• cat /dev/sndstat lists the audio devices that have been found on your system. The list is dynamic, i.e. when you plug in a USB audio device, it will appear in that list. The one marked as “default” will be used by most software by default, unless you specify a different device.
• gpart show gives a nice overview of the disk partitions (including file systems). geom -t produces similar information in a hierarchical, tree-like layout, although there are less details printed per entry. Another useful command is diskinfo -v ada0 to get detailed information about a certain disk (in this example it’s ada0 which is the first SATA drive).
