Linux driver
This adapter works with the irda-usb driver of 2.6 type kernels. To enable it, follow these steps:
Enable USB support: CONFIG_USB → <M> → Support for Host-side USB → USB support → Device Drivers CONFIG_USB_DEVICEFS → [*] → USB device file system → USB support → Device Drivers
Choose an appropriate USB host driver, one of: CONFIG_USB_EHCI_HCD → <M> → ECHI HCD (USB 2.0) support → USB support → Device Drivers CONFIG_USB_UHCI → <M> → UHCI HCD support → USB support → Device Drivers CONFIG_USB_OHCI → <M> → OHCI HCD support → USB support → Device Drivers
Enable IrDA support: CONFIG_IRDA → <M> → IrDA (infrared) subsystem support → Networking support → Device Drivers CONFIG_IRLAN → <M> → IrLAN protocol → IrDA (infrared) subsystem support → Device DriversNetworking support CONFIG_IRNET → <M> → IrNET protocol → IrDA (infrared) subsystem support → Device DriversNetworking support CONFIG_IRCOMM → <M> → IrCOMM protocol → IrDA (infrared) subsystem support → Device DriversNetworking support
Finally, enable the irda-usb driver: CONFIG_USB_IRDA → <M> → IrDA USB dongles → Infrared-port device drivers → Networking supportIrDA (infrared) subsystem support (Device Drivers)
Compile your kernel with these options (don't forget # depmod -ae) and reboot or just load the relevant modules (usb, usb-ehci/usb-uhci/usb-ohci, usb-storage, irda, irlan, irnet, ircomm, ircomm_tty, irda-usb). Attach the IrDA adapter to the UltraPort, if not done already.
Do a # cat /proc/bus/usb/devices to asure yourself that your IrDA adapter is recognized by the USB subsystem.
