Known issues

Linux

On Linux there is an issue when uploading the firmware because of a kernel module (http://ubuntuforums.org/showthread.php?t=1123633). If you can't upload the firmware with your Linux OS, add blacklist cdc_acm at the very end of the file /etc/modprobe.d/blacklist.conf. Afterwards execute sudo rmmod cdc_acm. This will remove the cdc_acm module from the kernel and prevent its restart. Now try to flash the firmware again.

Another issue is that the development package of libusb has to be installed. On Ubuntu you can do this by using sudo apt-get install libusb-dev.

Furthermore, to use USB connection, a java library has to be compiled via ant. To do this perform cd /path/to/leJOS/build and start ant. If the ant build tool is not installed on your system, you can do so via sudo apt-get install ant.
