罗技 Unifying 接收器是无线设备的接收器，可同时连接最多六个兼容鼠标及键盘。 和该接收器一组的输入设备已预先配对，并能即插即用。而针对额外的输入设备，罗技仅提供 Windows 软件以供配对。 不过 Benjamin Tissoires 在 kernel mailing list 发表了一支程序，令 Linux 下也有其功能。

## 编译 unifying_pair

此程序亦可于 AUR 找到。

首先确定系统已安装了 C 编译器。

    # pacman -S gcc

将下列代码复制到文件并命名，假设名为 unifying_pair.c。

                       info.vendor != USB_VENDOR_ID_LOGITECH ||
                       (info.product != USB_DEVICE_ID_UNIFYING_RECEIVER &&
                        info.product != USB_DEVICE_ID_UNIFYING_RECEIVER_2)) {
                           errno = EPERM;
                           perror("The given device is not a Logitech "
                                   "Unifying Receiver");
                           return 1;
                   }
           }

           /* Send the magic sequence to the Device */
           res = write(fd, magic_sequence, sizeof(magic_sequence));
           if (res < 0) {
                   printf("Error: %d\n", errno);
                   perror("write");
           } else if (res == sizeof(magic_sequence)) {
                   printf("The receiver is ready to pair a new device.\n"
                   "Switch your device on to pair it.\n");
           } else {
                   errno = ENOMEM;
                   printf("write: %d were written instead of %ld.\n", res,
                           sizeof(magic_sequence));
                   perror("write");
           }
           close(fd);
           return 0;
    }

将源代码编译成可执行档 unifying_pair：

    $ gcc -o unifying_pair unifying_pair.c

## 兼容设备配对

下一步需要查找接收器设备的位置，因此观察下列命令的输出

    $ cat /sys/class/hidraw/hidrawX/device/uevent |grep NAME

(你必须把 X 替换成系统上存在的整数) 直到找到 Logitech USB Receiver 为止(在此假设 X 恰为 0)

    $ cat /sys/class/hidraw/hidraw0/device/uevent |grep NAME
      HID_NAME=Logitech USB Receiver

如果想要配对的设备现在是开着时，关掉并执行适才编译过的程序，以合适的设备做为其参数：

    # ./unifying_pair /dev/hidraw0

若顺利该程序会告知你打开欲配对的设备，且该设备应该也会正常运作。

## Known Problems

### Keyboard Layout via xorg.conf

With kernel 3.2 the Unifying Receiver got its own kernel module hid_logitech_dj which does not work flawlessly together with keyboard layout setting set via xorg.conf. A temporary workaround is to use xorg-setxkbmap包 and set the layout manually. For example for a German layout with no deadkeys one has to execute:

    $ setxkbmap -layout de -variant nodeadkeys

To automate this process one could add this line to xinitrc.
