I've had a report that with sane-backends 1.0.14 and 1.0.15, SANE
applications are giving this error when trying to scan with a USB
Epson Perfection 1250:

  sane_start: Device busy

Logs with SANEI_DEBUG_ variables set can be found here:

  https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=140248

It isn't a permissions problem: the /proc/bus/usb node is opened
without problem.

This part of the debug output might be relevant:

Any ideas?
