Bug 320591 – Upgrading to sane-backends-1.0.21 breaks Epson CX5400 flatbed scanner (epson2 driver)

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Andrew John Hughes 2010-05-19 16:20:48 UTC]

With 1.0.20 this scanner works fine.  It stops working after upgrading to 1.0.21.

scanimage -T returns scanimage: sane_start: Invalid argument after upgrading.  An strace of this shows repeated failures along these lines:

13284 ioctl(6, USBDEVFS_REAPURBNDELAY, 0xfff91868) = 0
13284 ioctl(6, USBDEVFS_SUBMITURB, 0xfff917d4) = 0
13284 ioctl(6, USBDEVFS_REAPURBNDELAY, 0xfff917b8) = -1 EAGAIN (Resource temporarily unavailable)

When SANE_BACKENDS is set to SANE_BACKENDS="epson epson2" it doesn't even pick the scanner up on scanimage -L.  Removing this at least picks up the scanner with scanimage -L but scanimage -T fails as above.

Reproducible: Always

strace of scanimage -T

[Comment 2 Patrick Kursawe (RETIRED) 2010-06-17 20:30:56 UTC]

Sorry, can't help you there.
I do not have the hardware to test this backend and there have been no changes to epson.c since February. It is officially unmaintained. Maybe you should file a bug upstream, I have no idea what's going wrong here. Perhaps you could do an strace with .20 and compare them to see what has changed?
Good luck...
