Fir Usb Irda 20 ^hot^ - U2irda Mini 4 Mbps

The U2IrDA Mini implements the IrLAP (Link Access Protocol) and IrLMP (Link Management Protocol) in firmware. On Windows, it uses a virtual COM port driver (e.g., from SigmaTel or Prolific) to expose IrCOMM services. Under Linux, it is recognized by the irda-usb driver kernel module, requiring the irattach daemon for stack initialization.
