>Description:
New port, USB/serial kernel module that supports the Arduino Uno . Current drivers do not recognize nor support the USB interface for this device, as it uses a scaled-down version of the ACM USB serial and has its own unique vendor ID and product ID combination.  I tried modifying existing drivers to accept this combination, but none of them would work, so I modified existing kernel source and created a driver that is similar to uplcom.  The product and vendor ID combinations are stored in a text file, files/ids.txt

X// Arduino UNO USB Serial Port Kernel Driver for FreeBSD

X// This is a user-modifiable file that can be used to add extra
X// USB Vendor ID / Product ID combinations to the list of existing
X// combinations that the driver recognizes as an Arduino Uno.
X//
X// If you modify your Arduino Uno (or obtain a similar unit with a different
X// Vendor/Product combination) you can simply modify this file to include
X// the new Vendor/Product information.
X//
X// Place your NEW Vendor ID / Product ID combinations below in the form of
X// a C-language structure initializer entry, as follows
X//
X//     { 0xaaaa, 0xbbbb },
X//
X// Where '0xaaaa' is the vendor ID, and '0xbbbb' is the product ID that you
X// want the driver to recognize as an Arduino UNO.  It must end with a ','
X//
X// The default value of { 0x2341, 0x0001 } is already included as a reference.
X// NOTE:  do not remove or modify this entry unless you really really mean it.
X//
X// If you change this file, you will need to update it each
X// time you obtain a fresh copy of the ports tree.

XThe Arduino Uno (http://arduino.cc/) is an open source hardware micro-
Xcontroller designed primarily for prototyping and experimentation.
XAlthough the devel/arduino port already exists for programming the device,
Xit will not work properly with the newest Arduino hardware.  Previous
Xversions of the Arduino used an FTDI USB to Serial interface.  The newest
XArduino (beginning with the Uno) uses an on-board ATMel 8U2 controller
Xto emulate a USB to Serial interface with its own custom Vendor ID and
XHardware ID.  As a result, NONE of the existing FreeBSD USB to serial
Xdrivers can work with it.  This kernel driver supplies the necessary
Xkernel support for the Arduino Uno on FreeBSD.
X
XAdditionally, some 'ACM' USB Serial devices may work with this driver by
Xmanually adding their Vendor ID and Product ID combination to files/ids.txt

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