Here's the new log, after recompilation with your hack. <br>I attached it all, zipped, since its end looked somewhat promising, to me. ;)<br><br>Twain28<br><br>> Subject: Re: [sane-devel] Testing on Canon MF6580PL<br>> From: nicolas0martin@gmail.com<br>> To: twain43@hotmail.com<br>> CC: sane-devel@lists.alioth.debian.org<br>> Date: Thu, 10 Jun 2010 21:45:21 +0200<br>> <br>> I don't know the current status of Darwin libusb against usb interrupts,<br>> but it used to not support timeouts in older versions, which makes pixma<br>> backend unusable for some PIXMA models. <br>> <br>> Looking at the Darwin libusb 1.13 source files, comments show this may<br>> be working now, but not sure (source code still contains a message about<br>> timeouts not being supported). <br>> <br>> Anyway, I added a while back a very ugly hack in the pixma backend, that<br>> used to work for some PIXMA devices (use a read bulk instead of a read<br>> interrupt) but it may fail with others. <br>> What I can propose to you is to give a try without this hack, to check<br>> if this is better now with the current Darwin libusb. <br>> <br>> So please replace your current git file:<br>> sane-backends/backend/pixma_io_sanei.c with the one I've attached,<br>> recompile/reinstall, and give another try as you did just previously<br>> (with the 3 exports statements). <br>> And send back the new scanimage.log you'll get.<br>> <br>> Nicolas<br>> <br>> Le jeudi 10 juin 2010 à 09:29 +0000, twain43@hotmail.com a écrit :<br>> > Here's the new log, obtained following your instruction.<br>> > I'm on Mac OS X 10.5.8, Libusb 0.1.13 beta 2009-09-10 (got from TWAIN<br>> > SANE project page).<br>> > Crossing my fingers for a miracle....<br>> > <br>> > Twain28<br>> <br> <br /><hr />Messenger Radio. <a href='http://www.messenger.it/messenger_radio.aspx' target='_new'>La radio che si fa cliccare!</a></body>
