让爱普生完美的V39扫描仪在拱门工作？

Question

我正在努力让爱普生完美的V39扫描仪在拱门工作。它是USB扫描仪，直接从USB端口获得电源。

% sane-find-scanner
found USB scanner (vendor=0x04b8 [EPSON], product=0x013d [Epson Perfection V39]) at libusb:001:002

尝试扫描图像：

% scanimage -L

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).

还有其他各种发行版的.deb和.rpm包，但这里没有用于Arch的包：
