2.3.3
Not all USB devices require user-provided device drivers. Some types of USB-related
drivers are provided by and distributed along with the operating system. For example,
modern versions of Windows, Linux, and Macintosh operating systems are distributed
with Human Interface Device (HID) class USB drivers. Upon detecting the connection
of a HID class USB device, such as a mouse, the operating system automatically uses
the built-in drivers, and no user-provided driver installation is required.
The PICDEM FS USB Demo Board comes preprogrammed with custom device class
firmware, which relies on the Microchip general purpose USB driver. Since this driver
is not provided with the operating system, it is necessary to manually install the driver
before the PICDEM FS USB Demo Tool can be used.
When the Found New Hardware Wizard appears after plugging in the device, Windows
will be looking for a *.inf file with a USB Vendor ID (VID) and Product ID (PID) match-
ing the VID and PID programmed into the USB firmware. When the wizard appears,
use the “Browse” feature to manually point it to the .inf file located in the MCHPUSB
Driver Release directory, as indicated in the MCHPFSUSB release notes. In
MCHPFSUSB release version 1.2, the .inf file will be found in the
C:\MCHPFSUSB\Pc\MCHPUSB Driver\Release directory.
The .inf file is a short, plain text installation instructions file. This file may be edited in
text editors, such as Notepad. Among other things, the .inf file lets the Windows oper-
ating system know what driver binary files (ex: mchpusb.sys) it should use with the
new hardware, what text strings should appear in the device manager describing the
device and what (if any) special registry entries should be made for the new hardware.

and launch the Found New Hardware Wizard. For additional assistance, refer to
Chapter 6. “Troubleshooting”.
