But since working and non-working | | situations are very reproducible, I suppose it is not an hardware | | problem. | | In particoular, the camera works in linux on the both conditions (both | | necessary): having worked in windows and the laptop having been | | rebooted from windows. And for working in windows, a "deep" boot is | | necessary (ie a boot from a completely "shut down" situation). Sorry | | for the terms used, but I don't know how to express better the two | | different kinds of booting. Hope them were understandable. | | | | Well, thank you all for reading and for any suggestion you will write. | | | | Ok, so the windows driver probably does some initialization that we | miss. In order to help you further I need some usb snoops from windows. | This page [1] gives some good instructions on how to capture usb sniff | logs. Follow them and put them up somewhere on the web and send the | links to this mailing list. | |> Ok, it should be here: http://www.gest.unipd.it/~zanardo/snoop/snoop.zip | | Thanks, | Erik | Hi, I've investigated your usb snoop and couldn't find anything new. I've added some more init code from your snoop to the m5602-mt9m111 test branch. Please update to the latest svn and check if this branch works with livecam in bayer mode @ 640x480 when you _haven't_ used windows and rebooted before. Let me know if it works better.
