掃描器 GT-1500 Epson 無法通過 xsane、simple-scan 或 iscan 找到
目前我正在嘗試讓我的 Epson GT-1500 工作。我正在使用基於 debian stretch 9 的 Sparky Linux 5.0.4-amd64。
sane 不支持掃描器 Epson GT-1500,因此需要從 Epson 網站下載適當的 Iscan-Driver。安裝後我做了以下手動步驟:
/etc/sane.d/ddl.conf,修改:
epson to #epson epson2 to #epson2
因為 /etc/sane.d/epkowa.conf 在那裡!
然後編輯了epkowa.conf:
usb 0x04b8 0x0133
然後我編輯了/lib/udev/rules.d/60-libsane.rules:
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0133", ENV{libsane_matched}="yes" # Epson GT-1500 | Epson GT-1500
重新啟動後,仍然沒有成功。然後我創建了 /etc/udev/rules.d/99-epson-gt1500.rules
ACTION!="add", GOTO="epson_rules_end" SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GOTO="epson_pid_test" SUBSYSTEM!="usb", GOTO="epson_rules_end" LABEL="epson_pid_test" # Check for the gt-1500. ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0133", OWNER="root", GROUP="root", MODE="660" LABEL="epson_rules_end"
重啟,沒有成功。
在我執行scanimage -L的每一步中:
這個過程花了很長時間但列印出來:
device `epkowa:usb:001:003' is a Epson (unknown model) flatbed scanner
但 iscan、simple-scan 和 xsane 要麼停止工作(簡單關閉),要麼給出消息“未找到掃描器”
sane-find-scanner 的輸出:

使用和不使用 sudo 執行所有內容。
和更多資訊:
scanimage -x 100 -y 100 --format=tiff >image.tiff scanimage: open of device epkowa:usb:001:003 failed: Access to resource has been denied
作為 sudo 執行它需要很長時間,但不會掃描任何圖像….
在清除並重新安裝 iscan 後我注意到的一些事情:
Entpacken von iscan-network-nt (1.1.1-1) ... iscan-data (1.36.0-1) wird eingerichtet ... expr: Syntaxfehler tail: ungültige Anzahl von Zeilen: „/lib/udev/rules.d/60-libsane.rules“ iscan (2.30.1-1~usb0.1.ltdl7) wird eingerichtet ...
我不確定此錯誤是否可能導致掃描無效。文件的內容看起來不錯,但至少我認為是這樣。
執行: sudo strace -o strace.out -f scanimage -T 給了我:
5199 access("/usr/lib/iscan/esdip", X_OK) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden) 5199 openat(AT_FDCWD, "/dev/bus/usb/001/003", O_RDWR) = 12 5199 ioctl(12, USBDEVFS_GETDRIVER, 0x7ffcebbc2220) = -1 ENODATA (Keine Daten verfügbar) 5199 ioctl(12, USBDEVFS_CLAIMINTERFACE, 0x7ffcebbc237c) = 0 5199 ioctl(12, USBDEVFS_SUBMITURB, 0x7ffcebbc2230) = 0 5199 ioctl(12, USBDEVFS_REAPURBNDELAY, 0x7ffcebbc21f8) = 0 5199 ioctl(12, USBDEVFS_SUBMITURB, 0x7ffcebbc2230) = 0 5199 ioctl(12, USBDEVFS_REAPURBNDELAY, 0x7ffcebbc21f8) = 0 5199 ioctl(12, USBDEVFS_SUBMITURB, 0x7ffcebbc2230) = 0 5199 ioctl(12, USBDEVFS_REAPURBNDELAY, 0x7ffcebbc21f8) = -1 EAGAIN (Die Ressource ist zur Zeit nicht verfügbar) 5199 select(13, NULL, [12], NULL, {tv_sec=0, tv_usec=1000}) = 0 (Timeout)
然後最後一行在無限循環中重複……有什麼想法嗎?
我發現了問題!當我第一次下載 iscan 驅動程序時,它是以下版本:
iscan-bundle-1.0.0.x64.deb.tar.gz
但不知何故,我雖然必須有一個更新的版本,但在愛普生網站上搜尋了幾個小時讓我找到了一個名為:
iscan-gt-1500-bundle-1.0.1.x64.deb.tar.gz
在使用不帶 sudo 的捆綁 install.sh 腳本安裝此程序後,掃描器在第一次嘗試時就做出了反應,我能夠使用 xsane 掃描頁面……即使沒有重新啟動我的系統!現在我設置了掃描器組,我希望現在一切都好。
我在這裡得到了(工作的)gt-1500-bundle:
http://support.epson.net/linux/en/iscan.php?model=gt-1500&version=1.0.1
最後,在將我的登錄使用者添加到掃描器組之後
usermod -a -G scanner myusername
然後重新啟動,我可以在沒有 sudo 權限的情況下進行掃描。
