+^^^^^^^^^^^^^^^^^^^^^^
+
+The NuttShell (NSH) Nucleus 2G can be modified in order to support
+USB host operations. To make these modifications, do the following:
+
+1. First configure to build the NSH configuration from the top-level
+ NuttX directory:
+
+ cd tools
+ ./configure nucleus2g/nsh
+ cd ..
+
+2. Then edit the top-level .config file to enable USB host. Make the
+ following changes:
+
+ CONFIG_LPC17_USBHOST=n
+ CONFIG_USBHOST=n
+ CONFIG_SCHED_WORKQUEUE=y
+
+When this change is made, NSH should be extended to support USB flash
+devices. When a FLASH device is inserted, you should see a device
+appear in the /dev (psuedo) directory. The device name should be
+like /dev/sda, /dev/sdb, etc. The USB mass storage device, is present
+it can be mounted from the NSH command line like:
+
+ ls /dev
+ mount -t vfat /dev/sda /mnt/flash
+
+Files on the connect USB flash device should then be accessible under
+the mountpoint /mnt/flash.
