在Ubuntu中使用兼容HID的鼠标（例如设备）

8

目的：我有一个模仿鼠标的白板。因此，当您单击并拖动白板时，它应该移动光标。我想在Ubuntu中使白板工作在Windows上工作。设备信息：其输出cat /proc/bus/input包含设备信息

由于bInterfaceProtocol为None，Linux不会将其识别为鼠标输入设备。

从Windows对其进行反向工程以使其在Linux中工作的理想方法是什么。

“从Windows进行逆向工程的理想方法是什么”：您不需要对其进行逆向工程，驱动程序已经就位，并且将其称为“ usbhid”。该命令的输出是什么usb-devices | grep -A5 'Vendor=4623 ProdID=011a' | grep Driver？另外，尝试断开连接，然后再次连接设备，然后运行dmesg。说什么

@SamProtsenko添加了，请检查。

好了，驱动程序就位了，您只需要告诉Linux（用户空间部分）您的设备就是鼠标即可。我没有发现自己在这样的情况下，但如果我是你，我会尝试指定xorg.conf中（通过搜索InputClass，MatchVendor，MatchProduct关键字），或试图替代bInterfaceProtocol和bInterfaceSubclass使用udev规则。
— Sam Protsenko '16
根据您提供的dmesg输出，它似乎被识别为触摸屏，而不是鼠标（hid-multitouch加载驱动程序）？

我写了能够做到这一点的脚本。但是我必须弄清楚设备的输入是什么意思。
