私のAIOプリンタ/スキャナはCanon E400ですが、通常のユーザーとして私のスキャナを見つけることができません。 sudo&scan または sudo のみ使用できます。

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).

また、/lib/udev/rules.d/60-libsane.rulesに追加しましたが、まだ機能しません。
SUBSYSTEM=="usb", ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="177a", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes"
答え1
この行を追加してこの問題を解決してください。/lib/udev/rules.d/10-local.rules
ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="177a", MODE="0666"
答え2
scanner
、、にアカウントを追加しましたlp
。saned
しかし、それだけでは役に立ちません。これらのルールファイルがないので、私のソリューションはsudo chmod -R a+w /dev/bus/usb
。その後、sane-find-scanner
通常のユーザーアカウントを使用して検索できることを確認できます。
rc.local
その後、次の内容を含むファイルを追加/作成しました。
#!/bin/sh -e
chmod -R a+w /dev/bus/usb
exit 0
それから私はそれを設定しましたsudo chmod +x rc.local
。
