Why not just use a slower, cheaper 115.2 kbps dongle? Because many industrial devices require FIR for firmware flashing. For example, a medical glucometer that stores 500 readings will transfer data in 12 seconds over 4 Mbps FIR versus nearly 3 minutes over SIR. The explicitly supports the 4 Mbps FIR mode, which requires precise timing and a clean USB host controller. U2IrDA Mini 4 MBPS FIR USB IrDA 20
