IrDA Control Host Controller with USB Interface User
s Guide
USB-Enumeration for Peripherals
Table 15 represents the request and the relative data sequence between the Host device
(Windows 98 Operating System) and the USB Dongle, where the USB Dongle is USB-
Enumerated to the Host, and the IrDA Control Peripheral is newly bound under the condi-
tion that USB Dongle is operating at Configuration [2] (Bridge Mode).
