升级到Linux Mint 18后，扫描程序不再起作用

Question

从Linux Mint 17.3迁移到Linux Mint 18.1后，我的扫描仪不再工作了。我的扫描仪是Epson Stylus SX445W。

在执行命令scanimage -L之前，我只能看到一个扫描仪。现在我有两个，而只有一个扫描仪连接到计算机：

$ scanimage -L
device `epson2:libusb:002:008' is a Epson PID 0884 flatbed scanner
device `epkowa:usb:002:008' is a Epson Stylus TX435W/NX430/SX440W 
Series flatbed scanner

有没有人有这个问题，以及如何获得提示来解决它？谢谢！

Answer 1

我终于找到了解决方案。如果它可以帮助某人，我在这里发布。

对于Linux Mint 18之前的版本，Epson驱动程序是使扫描仪工作所必需的，但不再是这种情况（支持开箱即用）。

为此，我们需要删除此驱动程序的deb包：packages isane *。

删除它们后，执行以下命令：

$ sudo sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

could not fetch string descriptor: Pipe error
could not fetch string descriptor: Pipe error
found USB scanner (vendor=0x04b8, product=0x0884) at libusb:002:010
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

之后，我可以使用命令scanimage -L在列表中看到我的扫描仪：

$ scanimage -L
device `epson2:libusb:002:010' is a Epson PID 0884 flatbed scanner

然后我们可以使用XSane再次使用扫描仪！
