IrDA Control Host Controller with USB Interface User

Description of these two operation modes is given in Table 2.
Dongle Driver
When initiating the IrDA Control peripheral to communicate with the Host device with Win-
dows 98 boot, the Dongle Driver must be properly installed into the Windows 98 operating
system prior to the actual communication. Once this driver is installed to the PC, the Don-
gle Driver will be loaded on the Host when the USB Dongle is connected, which will be con-
figured to the bridge mode (Configuration value: 2).
The Dongle Driver recognizes the connected IrDA Control peripherals (Keyboard, Mouse)
as USB peripherals (USB keyboard, USB mouse), for which the HID drivers already pro-
vided on the Windows 98 operating system can be utilized. Installing this
Dongle Driver
on the Host (PC) will allow end users to utilize new IrDA Control peripherals without install-
ing drivers unique to the peripherals.

OPERATION MODE DESCRIPTION
Emulation
Mode
1
The dongle can emulate itself as a general wireless key-
board with pointing device capability (e.g. mouse) under
this mode. Endpoint 1 is used for the keyboard data trans-
mission. Endpoint 3 for mouse data transmission.
In this mode, the dongle will perform as the USB Dongle.
IrDA Control keyboards and mice will be recognized as
USB keyboard or mice in Host PC HID class. In this case,
HC will allow several Peripherals to share a single End-
point, and virtually perform as if it has multiple Endpoints for
the Host PC. This mechanism will allow multiple peripherals
to be connected to a single dongle, but the
Dongle Driver
needs to be installed to support USB Dongle function.
