使用我的扫描仪的最后一步是什么？
提问于 2014-12-22 00:27:17
我有佳能的DR-1210C USB扫描仪。
当插入时，内核会识别它：
[5365651.911506] usb 2-2.1: USB disconnect, address 3
[5365661.952066] usb 2-2: USB disconnect, address 2
[5365683.268060] usb 2-2: new full speed USB device using uhci_hcd and address 4
[5365683.441019] usb 2-2: New USB device found, idVendor=1083, idProduct=160f
[5365683.441027] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[5365683.441033] usb 2-2: Product: CANON DR-1210C
[5365683.441037] usb 2-2: Manufacturer: CANON
[5365683.441248] usb 2-2: configuration #1 chosen from 1 choicesane-find-scanner可以看到它：
# sane-find-scanner will now attempt to detect your scanner. If the

# No SCSI scanners found. If you expected something different, make sure that

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).我错过了什么？我试着遵循这个方法，但是它并没有给我任何基于故障排除建议的洞察力。

如果运行scanimage的用户没有访问设备的权限，这是典型的情况。您可以使用以下方法检查设备所属的组：
ls -la /dev/bus/usb/002/004( 002/004部件是从sane-find-scanner输出中提取的)，并确保用户saned是拥有设备的组的成员。确保在更改后重新启动saned守护进程。
