Bugzilla Bug 157608

Don

Don´t know if this is an upstream bug or gentoo-specific.
Facts:

printer Kyocera FS-820 worked with cups 1.1
does not work with cups 1.2, because an ioctl in the usb-backend fails:

heinrich backend # pwd
/usr/libexec/cups/backend

heinrich backend # emerge -pv cups

These are the packages that would be merged, in order:

Created an attachment (id=104542) [details]
patch for getting Kyocera FS 820 with cups-1.2 (kernel issue) based on kernel
2.6.18-r4

The patch modifies the file usblp.c in /usr/src/linux/drivers/usb/class/. It
adds a line that marks Kyocera FS-820 as "quirky". 

Martin, can you please send this patch to the LKML?

dsd_, can you please include this patch in the gentoo sources?

Stefan, I

Stefan, I´ll try to send it. Have to read how to do that correctly. Will do it
the next days.

I'm happy to submit it on your behalf if you would like, just provide a full
name so that I can ensure you get credited

Created an attachment (id=104569) [details]
patch in diff -up style based on vanilla 2.6.19 sources

I have mailed the patch upstream in the hope that it gets included or a better
solution can be found.

Fixed in gentoo-sources-2.6.19-r5
