Scanner Button Daemon

I recently purchased the Lide 110 and tried to get the scanner buttons working on my ubuntu home server using scanbuttond. But after a day of trying to compile everything, I figured two things: 1. The genesys backend that is available from older versions of scanbuttond works only with lower versions of the Canon Lide series, including Lide 100 and 200. 2. The USB protocol and handshake have changed in the Lide 110 and Lide 210. So even if you manage to get it all compiled, the old genesys backend no longer works. So I started to dig into the various information on the internet and have finally figured a way to get this working by changing the genesys.c source. I have also documented the same on my personal blog. URL's are prohibited, but you could google for "vinayaga raman scanbuttond blog canon lide 110" to get there. And no guys, this is not to make my blog popular, I spent over a week of painstaking work in getting this working, so I hope this helps folks looking to solve the same problem with Canon Lide 110 and Canon Lide 210.

Nice and simple modularly built application

I tested scanbuttond version 0.2.3.1 on my Raspberry Pi with a Canon CanoScan LiDE 25 Scanner. Everything is working fine! The buttonpressed.sh script is executed exactly once at every push of a button (with one little exception, see below) and gets the correct number. The only little glitch is, if you push a button multiple times fast in a row, there is only one event detected. If you push another button after that, you sometimes have to wait some seconds (up to 15) until the buttonpressed.sh script is executed. But this should not be a common use case as you normally would push only one button and wait for the action to be completed. Thank you very much for your awesome work! It helps a lot in my project to build a network enabled scan-and-print combination with a Raspberry Pi, an old scanner and a cheap usb printer.

Scanbuttond is wonderful! Thanks.

Very good, it works very well.
