have you run make?

You can also get it working with the CVS version of Lejos
and a Linux kernel >= 2.6.7, which includes the newest driver.
To get and install Lejos from CVS do
$ cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/lejos login
$ cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/lejos co -P lejos
$ cd lejos
$ make
The driver module should be loaded:
$ lsmod | grep lego
legousbtower 15360 0
There should be a device node for the USB tower
(if you have udev this will be created when you plug in the tower):
$ ls -l /dev/usb/legousbtower*
crw-rw-rw- 1 root root 180, 160 2005-02-12 21:39 /dev/usb/legousbtower0
Set RCXTTY to /dev/usb/legousbtower0
You should now be able to use it,
use lejosjc, lejoslink, lejosdl and firmdl from the bin directory.
(some options may have changed).
Since you want to do communication, take a look at examples/comms
(the Makefiles need also some updating).
Hope this helps
Jürgen

| Hi Juergen, Thank you for your answer. Some questions though: (...) Yes, I did. That solved some problems. (...) Does CVS work with my 2.4.26 kernel as well? Should I remove the 'old' leJOS version first? (...) Thanks Huub (20 years ago, 13-Feb-05, to lugnet.robotics.rcx.java)
