Brother MFC-7420 installed under fresh install of 18.04 and connected via USB. Brother2 drivers are installed. Have created links and local udev rules and almost have scanner working.
scanimage -L >>> device `brother2:bus2;dev4' is a Brother MFC-7420 USB scanner scanimage --test >>> scanimage: open of device brother2:bus2;dev4 failed: Invalid argument Using debug, scanimage test openned and successfully interrogated the scanner but failed with [dll] sane_start(handle=0x55c29b5b7ee0) scanimage: sane_start: Invalid argument scanning to file was similar [dll] sane_open: trying to open `brother2:bus2;dev1' scanimage: open of device brother2:bus2;dev1 failed: Invalid argument To get this far my drivers needed libusb-0.1-4 (userspace USB programming library). 18.04 uses libusb-1 and they are not interchangeable as I tried a simple link pointing to new version. Is this a jigsaw puzzle with a couple of pieces missing -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1728012 Title: Many 3rd party scanner drivers are broken by a sane change Status in sane-backends package in Ubuntu: Confirmed Bug description: Many scanners can no more be used since sane has changed something: The 3rd-party plug-in the vendor provides as .deb package will still install. But the scanner is no more recognized. Scanners that are affected are(besides others): - Epson Perfection V10 - Epson Perfection V1000 - Epson WorkForce GT-1500 - Brother MFC-8510DN - Epson Perfection V33 It is to note that the probability that the scanner manufacturers fix things others broke is below 100%.
