Well, I got a hold of a Windows XP laptop finally to get some usb logs. I hope someone can make sense of these because I'm fairly clueless.
I used the USB sniffer located here : http://benoit.papillault.free.fr/usbsnoop/index.php.en I got a log of plugging the scanner in and then unplugging it after it began idling here (about 5MB) : http://www.ford23.com/canon_lide_80/usbsnoop-plugin.log I made another log of a 300 dpi scan. I'm not sure if it's needed. It's about 180MB. : http://www.ford23.com/canon_lide_80/usbsnoop-300dpi_color.log If anything else is needed or if I didn't do something right let me know.

Register 6 cannot be the problem(its just state), so i guess the write to register 7 leads to an immediate reset. Regards, Pierre
