I just made a capture with SniffUSB of the replugging of the device and the scan of a little square in the middle of the plate with Canon's software. After the sensor went back to its original position and stopped moving I closed the log and saved it. It's about 50 MB long. Here you have it: http://dl.dropbox.com/u/6802765/replug-and-scan.log
As I have no Windows XP installed I had to use a virtual machine with a spare license I had in order to be able to use SniffUSB. It's curious that even I wasn't doing nothing with the scanner the log size kept increasing. I don't know if that's due to being on a virtual machine or if there's some kind of continous polling (there are big chunks of data full of zeros sent to the scanner). I haven't examined the log thoroughly, and I should refresh my USB knowledge to understand it completely. But in the raw information I could appreciate some simple patterns. Hope this helps someone. -- Si necesitas enviarme informaci?n como pueda ser un documento de texto, hoja de c?lculo u otros, utiliza el formato OpenDocument, est?ndar ISO/IEC 26300:2006.
