3. The board is functioning, but has stopped communicating with the Demo
In Demo mode, press and release S1, then reselect the board from the dropdown menu
and click on “Connect”.
In Bootload mode, press and hold S2 while resetting the board (pressing and releasing
S1), then reselect the board from the dropdown menu.
4. After switching from Demo mode to Bootload mode in the Demo Tool, the
The demonstration board’s default firmware behaves as two separate USB devices.
Invoking the bootloader firmware requires a special hardware signal, generated by
holding S2 while resetting the board (pressing and releasing S1).
Similarly, the board will not be available automatically when switching from Bootload to
Demo mode. In this case, it should only be necessary to reset the board (press and
release S1).
5. On running Bootload mode for the first time, the host system tries to repeat
Because the demo and bootloader firmware are essentially two separate pieces of
code with individual product IDs, the host system will see each as a separate device.
Each device will require the USB driver to be installed separately for it. Allow the
Windows Install Wizard to use the same .inf file used for the original driver
installation.

Make sure you are attempting to install the latest version of the driver. Older versions
of the custom driver did not support Windows Vista. The latest version of the custom
driver, as well as the latest versions of the USB reference projects, can be obtained
from: www.microchip.com/usb.

Make sure you are using the latest version of the custom class USB driver and the
PDFSUSB demo tool application. Older versions did not support Windows Vista. The
latest versions can be obtained from: www.microchip.com/usb. After downloading and
installing the package, the driver which Windows is actively using may still need to be
manually updated. Open the device manager, right click on the device and use the
“Update Driver” option to install the new version of the driver.
