[LAD] Novation launchpad midi driver

Although my provider's spam filter still blocks linux audio mails, I'm happy to announce my novation launchpad midi driver. It is not a driver in the common sense, but a user space usb application which offers a midi out and in to write and receive launchpad midi messages. On my distribution(gentoo) I needed to add myself to the usb group to run this application. Download it from: http://krampenschiesser.de/launchpadd-0.1.tar.bz2 Dependencies: I know the dependencies are quite fat(boost) but this driver is part of my sequencer application, and I just want to give launchpad owners the possibility to use their pad. boost >= 1.41 (need threads, signals2, foreach) libusb-1.0 alsa pthreads To build the whole stuff you need cmake(>=2.6). Installation: $ tar -xjf launchpadd-0.1.tar.bz2 $ cmake $ make $ sudo make install $ launchpadmidid To uninstall use : $ xargs rm < install_manifest.txt I would be very happy to get some feedback from the users and developers. Coming from the Java world this is my first(finished) project in c++ and c. And I didn't know anything about USB before... So if there is a developer who has got a good knowledge of c/c++ or usb interrupt transfers it would be great if he could have a look at the code, especially the method handleWriteTransfer in LaunchpadImpl(.cpp) is a point where I'm not that sure about the interrupt handling(although it works as it is right now). If there's anyone using this application on a kernel <=2.6.27 please inform me(as the polling changed with this version).
