Package: sane
Version: 1.0.14-1
Severity: normal
I'm using an Espon perfection 4990 scanner attached to a USB 2.0 port
The scanner works perfectly when attached to a real x86 box, but does
not on this box, neither in an ia32 chroot, nor native.
I've tried both epson and epkowa backends.
I'm not sure that the problem may not actually be either in the kernel
or in libusb.

[epkowa] sane_init, # SCSI scanners can be configured simply by listing the
path to the
[epkowa] sane_init, # device. For example, if your system claims to have a
/dev/scanner
[epkowa] sane_init, # SCSI device, all you have to do is uncomment the
following line:
[epkowa] sane_init, #
[epkowa] sane_init, #/dev/scanner
[epkowa] sane_init, #
[epkowa] sane_init, # In the interest of maintainability, most installations
would have
[epkowa] sane_init, # /dev/scanner sym-linked to the real SCSI scanner device
node.
[epkowa] sane_init, #
[epkowa] sane_init, # An alternative way that works for many operating systems
and is a
[epkowa] sane_init, # little bit more generic, is to have the backend probe
for your SCSI
[epkowa] sane_init, # scanner with the following configuration command:
[epkowa] sane_init, #
[epkowa] sane_init, scsi EPSON
[epkowa] sane_init,
[epkowa] sane_init, # On systems with libusb, the following line is sufficient
to get the
[epkowa] sane_init, # backend to recognise your USB scanners. It presumes,
however, that
[epkowa] sane_init, # the scanner---more precisely, it's USB product ID---is
known to the
[epkowa] sane_init, # backend.
[epkowa] sane_init, # For all USB scanners that are officially supported by
this backend,
[epkowa] sane_init, # this presumption is true. A list of such scanners can
be found in
[epkowa] sane_init, # sane-epkowa(5).
