+UHD - Device Identification Notes

+------------------------------------------------------------------------
+Identifying USRPs
+------------------------------------------------------------------------
+Every device has several ways of identifying it on the host system:
+
+* **Serial:** A globally unique identifier.
+* **Address:** A unique identifier on a network.
+* **Name:** An optional user-set identifier.
+
+The address is only applicable for network-based devices.
+See the USRP2 application notes.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Device discovery via command line
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+A "find devices" utility application comes bundled with the UHD.
+The find devices application will search for all devices on the host system and print the results.
+
+::
+
+    uhd_find_devices
+
+Device address arguments can be supplied to narrow the scope of the search.
+
+::
+
+    uhd_find_devices --args="type=usrp1"
+
+    -- OR --
+
+    uhd_find_devices --args="serial=12345678"
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Device discovery through the API
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The device::find() API call searches for devices and returns a list of discovered devices.
+
+::
+
+    uhd::device_addr_t hint; //an empty hint discovers all devices
+    uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+
+The hint argument can be populated to narrow the scope of the search.
+
+::
+
+    uhd::device_addr_t hint;
+    hint["type"] = "usrp1";
+    uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+
+    -- OR --
+
+    uhd::device_addr_t hint;
+    hint["serial"] = "12345678";
+    uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+
+------------------------------------------------------------------------
+Naming a USRP
+------------------------------------------------------------------------
+For convenience purposes, users may assign a custom name to their USRPs.
+The USRP can then be identified via name, rather than a difficult to remember serial or address.
+
+A name has the following properties:
+
+* is composed of ASCII characters
+* is between 0 and 20 characters
+* is not required to be unique
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Set a custom name
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Run the following commands:
+::
+
+    cd <prefix>/share/uhd/utils
+    ./usrp_burn_mb_eeprom --args=<optional device args> --key=name --val=lab1_xcvr
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Discovery via name
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The keyword "name" can be used to narrow the scope of the search.
+Example with the find devices utility:
+::
+
+    uhd_find_devices --args="name=lab1_xcvr"
+
+    -- OR --
+
+    uhd_find_devices --args="type=usrp1, name=lab1_xcvr"

-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
-

-
-    ./usrp1_serial_burner --old=12345678 --new=87654321
-
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 Specify a non-standard image
