Management Overview determines a USB IrDA Bridge gadget. Such gadgets are relied upon to supplant or supplement motherboard based handset executions.

The USB gadget trades IrLAP outlines between the host and the IrDA gadget. On the host, a USB driver courses the IrLAP casings to an IrLAP programming layer. IrDA applications ought not have the capacity to recognize that the IrDA gadget is associated utilizing USB.

The USB driver strips header data added by the USB gadget to IrDA gadget supplied outlines before conveying it to the host.

The gadget recognizes itself as an application-particular USB gadget.

All application-particular USB gadgets utilize the same class code (254). The USB-IF keeps up/allots each application specific USB gadget a one of a kind sub-class code. Application-particular USB gadget details allot convention codes as they require.
