[sane-devel] Does the Canon Lide 80 work?

[goland55 at aol.com]

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. :

If anything else is needed or if I didn't do something right let me 
know.

Thanks,

Aaron

Looks like we need an usb log from windows. Register 6 cannot be the
problem(its just state), so i guess the write to register 7 leads to an
immediate reset.
