Windows Vista/Vista64 Serial USB Driver for PIC18F2455
and PIC18F2450
When plugging a new USB device, Windows checks all its INF files to load the appropriate
driver. The INF file contains the Vendor ID, the Product ID or the USB Class
definition. If the VID/PID or the USB Class Definition of the USB device matches with
one INF file, Windows will load the driver described in this file.
There is no
driver required for Microsoft Windows as the adapter using the standard
Communication Device Class (CDC) driver
usbser.sys included in the
distribution. Windows doesn’t have a standard INF file for the CDC driver
and Microchip provides one. However, the INF file is not working with
Windows Vista as Vista doesn't have usbser.sys
in the system folder but only as part of another preinstalled driver. I
have updated INF file to support all
the version of Windows including Vista64. The installation procedure is
trivial.
Select the the driver INF file location:

Confirm the driver installation procedure...

and have your PIC18F2455 driver installed.
