* \subsection SSec_WindowsInstallation Windows Installation
- * On Windows systems, due to an unfortunate limitation of the USB AVR devices and the driver used in the official AVR
- * Studio/Atmel Studio platform, the programmer cannot be made compatible with AVRDude and AVR Studio/Atmel Studio at the
- * same time. Instead, the programmer will be compatible with the official Atmel software by default, with a recompilation
- * with the \c LIBUSB_DRIVER_COMPAT token (see \ref Sec_Options) being required to use the alternative libUSB driver
- * compatibility mode that will allow the programmer to work under AVRDude on Windows.
- *
- * If compiled for Atmel Studio/AVR Studio compatibility, install the Jungo device drivers that ship with the Atmel software.
- * If compiled in the alternative libUSB compatibility mode for AVRDude use, install the libUSB drivers that are included
- * with your compiled copy of AVRDude, or create them using the libUSB-Win32 (http://sourceforge.net/projects/libusb-win32)
- * project.
- *
- * For convenience, the programmer will report two different serial numbers depending on the firmware compatibility mode, so
- * that the correct driver can be installed for the matching firmware. If the \c RESET_TOGGLES_LIBUSB_COMPAT compile option
- * is used (see \ref Sec_Options) this allows for an easy way to automatically switch device drivers along with the firmware
- * compatibility mode. The serials are:

+ * On Windows systems, due to an unfortunate limitation of the USB AVR devices and the Atmel Studio platform, the programmer
+ * requires an alternative libUSB based driver. Uninstall the existing Jungo driver for the device (if installed) and replace
+ * it with the driver that ships with this project, to enable access to the programmer in Atmel Studio and AVRDUDE.
