Debian Jessie 无法检测到新的 Wacom Intuos (CTL490DB)

Question

我最近在计算机上安装了 Debian Jessie，并购买了一台新的 Wacom Intuos 平板电脑。我原本希望能够简单地将其插入并使用它，就像我过去在 Debian 上使用 Wacom 设备一样，但事实并非如此。

GNOME 的 Wacom 数位板配置工具完全无法检测到数位板，就像xsetwacom --list devices./dev/wacom不存在。

我尝试安装xf86-input-wacom，根据 Debian 维基，但是 apt 报告该包不存在。此外，wacom-tools尽管 WacomTablets 指南暗示它可能有助于使 Wacom 数位板工作，但却无处可寻。

每当我重新连接设备时，dmesg -w都会发现：

我遇到了同样的问题（相同的平板电脑，相同的操作系统），最后可以按照以下指南解决问题：

从头开始构建 wacom 的内核模块 - 花费了大约 10 分钟。
