Linux driver
This adapter works with the irda-usb driver of 2.6 type kernels. To enable it, follow these steps:
Enable USB support:
- Device Drivers → USB support → <M>Support for Host-side USB (CONFIG_USB)
- Device Drivers → USB support → [*]USB device file system (CONFIG_USB_DEVICEFS)
Choose an appropriate USB host driver, one of:
- Device Drivers → USB support → <M>ECHI HCD (USB 2.0) support (CONFIG_USB_EHCI_HCD)
- Device Drivers → USB support → <M>UHCI HCD support (CONFIG_USB_UHCI)
- Device Drivers → USB support → <M>OHCI HCD support (CONFIG_USB_OHCI)
Enable IrDA support:
- Device Drivers → Networking support → <M>IrDA (infrared) subsystem support (CONFIG_IRDA)
- Device Drivers → Networking support → IrDA (infrared) subsystem support → <M>IrLAN protocol (CONFIG_IRLAN)
- Device Drivers → Networking support → IrDA (infrared) subsystem support → <M>IrNET protocol (CONFIG_IRNET)
- Device Drivers → Networking support → IrDA (infrared) subsystem support → <M>IrCOMM protocol (CONFIG_IRCOMM)
Finally, enable the irda-usb driver:
- Device Drivers → Networking support → IrDA (infrared) subsystem support → Infrared-port device drivers → <M>IrDA USB dongles (CONFIG_USB_IRDA)
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.
