Thank you for analyzing and giving me great helps! Your guess was right, I saw errors in system.log when scanimage -L complained. Logs is like following: kernel[0]: USBF:69086.103 AppleUSBEHCI[0x28b9000]::Found a transaction which hasn't moved in 5 seconds on bus 253, timing out! kernel[0]: USBF:69092.103 AppleUSBEHCI[0x28b9000]::Found a transaction which hasn't moved in 5 seconds on bus 253, timing out! kernel[0]: USBF:69094.103 AppleUSBEHCI[0x28b9000]::Found a transaction past the completion deadline on bus 253, timing out! kernel[0]: USBF:69095.103 AppleUSBEHCI[0x28b9000]::Found a transaction past the completion deadline on bus 253, timing out! And now there's no log like that. My beginning question of 'no scanadf on Max OS X' is resolved at the same time. I learned we can get same functionality by using --source and --batch option. I write down the procedure for future help: tar xvzf libusb-0.1.12.tar.gz cd libusb-0.1.12 patch -p 1 < libusb-runloop.patch ./configure make && sudo make install make clean cd .. tar xvzf sane-backends-1.0.18 cd sane-backends-1.0.18 ./configure make && sudo make install make clean then connect the scanner /usr/local/bin/scanimage --source "ADF Duplex" --batch=hoge%d.tiff -- format=tiff Thank you very much Yoshi
