答案1
您面临的问题是：No SCSI scanners found。
答案也给出了：If you expected something different, make sure that you have loaded a kernel SCSI driver for your SCSI adapter.
看起来你需要安装一个后端。这http://manpages.ubuntu.com/manpages/precise/en/man5/sane-plustek.5.html 状态您可以使用sane-plustek，因此安装那个。

哦，还有……如果你看看我发布的链接：看起来 12.04 确实有这个包，而 12.10 还没有更新（手册中显示的是 12.04 包）。所以这解释了为什么它在 12.04 上能用，而在 12.10 上不能用
