[sane-devel] Problem with Canon Lide 220 scanner / sane / genesys: Device busy after computer start

[thillosen at free.fr]

Good catch!
Through update of my distro, packages "scanbd" and "scanbuttond" got 
installed, and this is what caused all the mess.
Now, I have uninstalled them, and everything is working flawlessly.

Thanks a lot for your help!
