USB HUB Host example(usb_host_hub) This example application demonstrates how to support a USB keyboard and a USB mass storage with a USB Hub. The application emulates a very simple console with the USB keyboard used for input. The application requires that the mass storage device is also inserted or the console will generate errors when accessing the file system. The console supports the following commands: "ls", "cat", "pwd", "cd" and "help". The "ls" command will provide a listing of the files in the current directory. The "cat" command can be used to print the contents of a file to the screen. The "pwd" command displays the current working directory. The "cd" command allows the application to move to a new directory. The cd command is simplified and only supports "cd .." but not directory changes like "cd ../somedir". The "help" command has other aliases that are displayed when the "help" command is issued. Any keyboard that supports the USB HID BIOS protocol should work with this demo application. The application can be recompiled to run using and external USB phy to implement a high speed host using an external USB phy. To use the external phy the application must be built with \b USE_ULPI defined. This disables the internal phy and the connector on the DK-TM4C129X board and enables the connections to the external ULPI phy pins on the DK-TM4C129X board. ------------------------------------------------------------------------------- Copyright (c) 2013-2014 Texas Instruments Incorporated.
