我有一台佳能 ScanFront，但它不再用作扫描仪。该设备包含一台运行某种 Linux 版本的单板计算机（uname-夫人回报Linux 3.10.87-cei.10_32-ltsi i686）。
通常，扫描仪会启动到具有触摸屏功能的 GUI。当我从扫描仪中提取 PCB 并启动它后，启动过程失败，并报告未找到扫描仪的错误，并将我踢出以 root 身份登录的类似 BASH 的 shell（这是一件好事）。
当我从 USB 驱动器启动到 Ubuntu 时，我可以进入 GNOME，但未检测到触摸屏。回到原来的发行版（很高兴我没有覆盖 SD 卡），我可以运行 lspci 和 lsusb，但我看不到触摸屏。
