删除多余的不工作的扫描仪

Question

我尝试将 USB 扫描仪添加到我的系统中，但没有任何运气，现在当我开始时X萨内或者图片扫描！对于Linux我得到了一份不工作的扫描仪列表。如何去除这些？

我试过了：

# pacman -Rsc iscan iscan-data sane xsane 
# rm -rf ~/.sane
# rm -rf ~/.xsane
# rm -rf /etc/sane.d

重新安装软件包后，仍然可以找到旧设备。我已经开机很多次了

# sane-find-scanner                                                                                        (10-06 19:05)

  # 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.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

found USB scanner (vendor=0x04b8 [EPSON], product=0x013d [Epson Perfection V39]) at libusb:004:003
  # 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.

检测到扫描仪。

# scanimage -L                                                                                             (10-06 19:07)

添加带有错误固件.bin文件的扫描仪的命令会丢失。
