无法以普通用户身份使用 Brother MFC-J625DW 扫描仪

我已经从 Brothers 网站上安装了 Brothers Linux 驱动程序，打印机功能似乎可以工作，但扫描仪功能无法工作。运行简单扫描时出现错误：无法连接到扫描仪。我的打印机/扫描仪已通过 USB 连接。Ubuntu MATE 14.10 64 位。

我注意到我可以使用 sudo 运行扫描仪，所以我猜测我存在权限问题。

这里的问题是如何允许普通用户在没有提升权限的情况下运行我的扫描仪。

我在下面列出了一些我进行故障排除的输出。

lusb 显示：

理智查找扫描仪：

答案1

因此我无法测试这一点，因为无法访问 USB 扫描仪，但是我看到一个/etc/groups名为scanner

您可以尝试将用户添加到该组然后注销并以该用户身份重新登录并进行测试吗？

sudo usermod -a -G scanner usernamehere

答案2

作为解决方案，Brother 提供了一个.deb可下载的软件包这里。可以通过单击文件或使用以下命令进行安装：

dpkg -i brother-udev-rule-type1-1.0.0-1.all.deb
