I connected the MX850 to a 17" flat-panel iMac running Mac OS X 10.4.11, using a different USB cable. I installed gettext 0.17, libusb 0.1.13 beta 2009-02-22 and sane- backends 1.1.0-cvs 2009-02-20 as packaged for Mac OS X 10.4 by Mattias Ellert. And then I restarted the iMac. Then $ cd ~/Desktop $ mkdir scanning_from_the_command_line $ cd scanning_from_the_command_line $ mkdir 2009-03-26.testing $ cd 2009-03-26.testing $ export PATH=/usr/local/bin:$PATH $ export SANE_DEBUG_SANEI_USB=255 $ export SANE_DEBUG=255 $ export SANE_DEBUG_PIXMA=20 $ sane-find-scanner &> sane-find-scanner.log found USB scanner (vendor=0x04a9 [Canon], product=0x172c [MX850 series]) at libusb:007:002-04a9-172c-00-00 $ scanimage -L &> scanimage-L.log device `pixma:04A9172C_21B0DA' is a CANON Canon PIXMA MX850 multi- function peripheral $ scanimage -d pixma:04A9172C_21B0DA -T &> scanimage.log scanimage hangs as on the OS 10.5 iMac, seemingly at the same place as on the OS 10.5 iMac. This time at least kill -9 managed to kill it. system.log shows KernelEventAgent[34]: tid 00000000 received unknown event (12) Interestingly, closing the Terminal window (since it seems to be irretrievably hung despite having killed scanimage), opening a new Terminal window, and doing the above all over again results in scanimage hanging seemingly at the same place, but this time the scanimage process is not killable, and the system.log shows kernel[0]: USBF: 952.776 AppleUSBOHCI[0x1a30800]::DoIOTransfer - error 0xe00002eb queueing request This is repeatable on the 10.4 iMac: the first attempt at scanimage -T immediately after restarting results in the KernelEventAgent message and the scanimage process is killable. The second scanimage -T results in the kernel USBF message and the scanimage process is not killable. The complete logs for the first and second runs are available at http://members.shaw.ca/schoenrank.ca/2009-03-27_sane_testing/ and http://members.shaw.ca/schoenrank.ca/2009-03-27_sane_testing.2/ Peter ----- Peter Schoenrank mailto: peter at schoenrank.ca phone: 250-655-6753 -------------- next part -------------- An HTML attachment was scrubbed...
