The USB UIRT allows any USB-equipped PC to transmit and receive infrared signals. LIRC 0.8.1 supports the USB-UIRT natively. LIRC 0.7.1 does not support the USB-UIRT natively, but the patch listed below can be used.

Patch for LIRC 0.7.1: http://www.gemair.com/~neveld/usb-uirt/lirc-0.7.1-usb_uirt.patch.bz2
Utility
The manufacturer produces a (Windows) helper utility for this remote. It allows the user to set the usb wake-from-standby key. This means you can suspend your machine to S3 (Suspend to RAM), then wake it up with a button on your remote control (NOTE: this feature doesn't appear to function properly under linux). Also, it has several other features, including turning off the blinking response to IR signals. The current verstion is at: http://www.usbuirt.com/lrnhelper_0_0_5.zip
LIRC 0.7.1 Installation
# tar xvfj lirc-0.7.1.tar.bz2 # cd lirc-0.7.1 # bzcat ../lirc-0.7.1-usb_uirt.patch.bz2 | patch -p1 # ./setup.sh
Choose Driver Configuration, USB Devices, USB-UIRT2(receive and transmit)
Save Configuration & Exit
Edit configure.sh
#!/bin/bash ./configure \ --with-moduledir=/lib/modules/2.6.15-gentoo-r1/misc \ --with-tty=/dev/ttyUSB0 \ --with-x \ --with-syslog \ --with-driver=usb-uirt2_raw \ --with-major=61 \ --with-port=none \ --with-irq=none \ --prefix=/usr \ "$@"
Compile
# sh ./configure.sh && make && make install
Gentoo Installation
In Gentoo, /etc/make.conf should contain
LIRC_DEVICES="usb_uirt_raw"
Emerge the lirc package
emerge -av lirc
Configure lirc, /etc/conf.d/lircd should contain
LIRCD_OPTS="-H usb_uirt_raw -d /dev/ttyUSB0"
Connect the USB-UIRT and start lircd
/etc/init.d/lircd start rc-update add lircd default
Kernel Driver Issue
Description of bug
The USB-UIRT uses a USB-to-serial adapter chip, and the Linux driver for this was broken after kernel 2.6.20 when changes to the parameters passed into the quirk functions resulted in a NULL pointer causing a kernel oops.
Partial Fix
A number of distributions are using a patched FTDI driver that solves the kernel oops, but is missing a critical fix to allow the USB-UIRT to work.
In /usr/src/linux/drivers/usb/serial/ftdi_sio.c locate the function ftdi_tiocmget and add "case FT232RL:" just after "case FT223C:". Then rebuild and install your modules.
Without this fix you will get an error from lircd about not being able to set DTR.
Resolution
This bug is confirmed fixed at some point prior to Ubuntu 10.10.
