Recetly 我试图通过固件更新来修复我的触摸板滞后，但它粉碎了我的整个触摸板。现在移动是倒置的，右键单击不起作用。
我的触摸板是 ELAN1200 04F3:304E，是有史以来支持最差的触摸板之一。
不过，我还是抱有希望的。
我知道触摸板被识别为 I2C-HID 设备，如果我可以用程序升级它的固件，就可以读取数据并将数据写入触摸板的芯片。
所以我正在尝试查找已连接的 i2c 设备，但 i2cdetect -l 没有运气。我的 lsusb 也不显示触摸板：

虽然 xinput 识别它：

我用来升级触摸板固件的程序在这里https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653456/comments/161
我有兴趣从工作的触摸板芯片复制数据并将其粘贴到我的。我该怎么做？
