The Arduino Uno (http://arduino.cc/) is an open source hardware micro-

controller designed primarily for prototyping and experimentation.
Although the devel/arduino port already exists for programming the device,
it will not work properly with the newest Arduino hardware.  Previous
versions of the Arduino used an FTDI USB to Serial interface.  The newest
Arduino (beginning with the Uno) uses an on-board ATMel 8U2 controller
to emulate a USB to Serial interface with its own custom Vendor ID and
Hardware ID.  As a result, NONE of the existing FreeBSD USB to serial
drivers can work with it.  This kernel driver supplies the necessary
kernel support for the Arduino Uno on FreeBSD.

Additionally, some 'ACM' USB Serial devices may work with this driver by
manually adding their Vendor ID and Product ID combination to files/ids.txt

+The Arduino Uno uses a specific vendor ID of 0x2341 and product ID of 0x0001
+
+If you modify your Arduino Uno to use a DIFFERENT vendor ID or product ID, you
+can add your vendor/product combination to the files/ids.txt text file
+according to the example shown.  Additionally, this driver MAY work with
+generic ACM USB Serial Devices.  You would need to manually add the
+vendor ID and product ID for these devices as well.  For ACM devices that
+are modems, consider using or modifyig the 'umodem' driver.
+
+You will need to load the uarduno kernel module before connecting the Arduino UNO
+via USB to your computer.  The command to manually load the driver is:
+
+  kldload uarduno.ko
+
+To automatically load the driver on startup, add the following line to
+your /boot/loader.conf file:
+
+  uarduno_load="YES"
