+------------------------------------------------------------------------
+Addressing the device
+------------------------------------------------------------------------
+A USRP1 can be identified though its 8 digit serial number,
+designated by the "serial" key in the device address.
+
+The device address string representation for a USRP1 with serial 12345678:
+
+::
+
+    serial=12345678
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Change the serial number
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The USRP1 serial number can be changed to any 8 byte string. Examples:
+
+::
+
+    cd <prefix>/share/uhd/utils
+    ./usrp1_serial_burner --new=87654321
+
+    -- OR --
+
+    ./usrp1_serial_burner --new=Beatrice
+
+    -- OR --
+
+    ./usrp1_serial_burner --old=12345678 --new=87654321
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Specify a non-standard image
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The standard USRP1 images installer comes with two FPGA images:
+ * **usrp1_fpga.rbf:** 2 DDCs + 2 DUCs
+ * **usrp1_fpga_4rx.rbf:** 4 DDCs + 0 DUCs
+
+By default, the USRP1 uses the FPGA image with 2 DDCs and 2 DUCs.
+However, a device address parameter can be used to override
+the FPGA image selection to use an alternate or a custom FPGA image.
+See the images application notes for installing custom images.
+
+Example device address string representations to specify non-standard firmware and/or FPGA images:
+
+::
+
+    fpga=usrp1_fpga_4rx.rbf
+
+    -- OR --
+
+    fw=usrp1_fw_custom.ihx
+
+    -- OR --
+
+    fpga=usrp1_fpga_4rx.rbf, fw=usrp1_fw_custom.ihx
+
+------------------------------------------------------------------------
+Specifying the subdevice to use
+------------------------------------------------------------------------
+The USRP1 has multiple daughterboard slots, known as slot A and slot B.
+The subdevice specification can be used to select
+the daughterboard and subdevice for each channel.
+For daughterboards with one one subdevice,
+the subdevice name may be left blank for automatic selection.
+
+Ex: The subdev spec markup string to select a WBX on slot B.
+Notice the use of the blank subdevice name for automatic selection.
+
+::
+
+    B:
+
+    -- OR --
+
+    B:0
+
+Ex: The subdev spec markup string to select a BasicRX on slot B.
+Notice that the subdevice name is always specified in the 3 possible cases.
+
+::
+
+    B:AB
+
+    -- OR --
+
+    B:A
+
+    -- OR --
+
+    B:B

+OS Specific Notes
+------------------------------------------------------------------------
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setup Udev on Linux
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+On Linux, Udev handles USB plug and unplug events.
+The following command creates a Udev rule for the USRP1
+so that non-root users may access the device:
+
+::
+
+    echo 'ACTION=="add", BUS=="usb", SYSFS{idVendor}=="fffe", SYSFS{idProduct}=="0002", MODE:="0666"' > tmpfile
+    sudo chown root.root tmpfile
+    sudo mv tmpfile /etc/udev/rules.d/10-usrp.rules
+    sudo udevadm control --reload-rules
+
