我正在尝试让一款廉价的 USB 游戏手柄在我的 Arm Chromebook 上运行的 Ubuntu 12.04 下工作（使用 chroot）。插入游戏手柄后，dmesg 显示：
[ 5879.411510] usb 2-1: new low-speed USB device number 8 using exynos-ohci

[ 5879.610584] usb 2-1: Product: USB Gamepad
lsusb 的输出是：

我没有/dev/input/ls0
ls -l /dev/input：

有任何想法吗？

答案1
DragonRise 游戏手柄使用 hid_dr 模块，可以使用 加载modprobe hid_dr。如果该模块不可用，则必须通过启用HID_DRAGONRISE内核选项来编译它（在 menuconfig 中，您可以在设备驱动程序 -> HID 支持 -> HID 总线支持 -> 特殊 HID 驱动程序 -> DragonRise Inc. 游戏控制器中找到它）。
加载模块后，设备将被正确识别并创建 /dev/input/js0。

答案2
除了缺失之外，js0它看起来不错。尝试modprobe joydev看看是否能给你一个/dev/input/js0。如果失败，请安装evtest，然后执行以下操作：
evtest /dev/input/event1
evtest /dev/input/event2
evtest /dev/input/event3
...
直到您找到游戏手柄。发布evtest启动时打印的信息，因为当无法将其检测为操纵杆时，按钮名称可能存在问题。
