Licence key

Licence key is a a HASP usb key. Packages are delivered with the package sold by CRC.

However, since Ubuntu 10.04 some tweaks must be done to have it working because of change in USB stack in Linux.

tweaks to simulate /proc/usb:

sudo mount --bind /dev/bus /proc/bus
sudo ln -s /sys/kernel/debug/usb/devices /proc/bus/usb/devices
sudo /etc/init.d/aksusbd restart
