UUU USB Failures
=======================


UUU exits without displaying anything
-------------------------------------

This indicates that your system is missing the ``libusb-1.0.dll`` required to run `UUU`. Put it right in place with ``uuu.exe``.

The most current version of UUU already includes ``libusb``. It is recommended to upgrade to the most current version, available at the `NXP's MFGTool v3 (i.e. UUU) Releases page @ github`_

.. note:: Also be aware that the ``uuu.exe`` if put in the ``PATH`` can be used system wide without relying on the included in UUU packages. This should be the preferred method.


Wait for Known USB Device Appear
--------------------------------
If you've already connected the board with your computer, pressing the RESET button might help. Also ensure you have set the bootmode jumper, for more see here: :ref:`enabling-bootmode`


TX8M-ND00 LIBUSB-HID-ERROR
--------------------------

Just run **UUU** again without resetting the board. We don't know why this happens, it seems to be a problem with uuu itself.
