About USB SEND example

Postby km7 » Thu Feb 20, 2014 12:59 am

Currently I can use nxt browse to upload the lejos nxt project in my NXT brick.Which works perfectly with no errors.

But if I use lejos pc project using example provided by org.lejos.pcexample, it simply tell me there is error messages.

The log is as followed:

USBSend Log.listener: Error: Failed to load USB comms driver.
USBSend Log.listener: Caused by lejos.pc.comm.NXTCommException: Cannot load NXTComm driver
USBSend Log.listener: at lejos.pc.comm.NXTCommFactory.newNXTCommInstance(NXTCommFactory.java:110)

USBSend Log.listener: at java.lang.ClassLoader$NativeLibrary.load(Native Method)
USBSend Log.listener: Failed to find any NXTs
USBSend Log.listener: Failed to connect to any NXT

Any ideas which part did I went wrong?

I am using OS X Marvericks 10.9 using usb connection.

How are you running your program? Take a look at the shell script used to run nxjbrowse and make sure you are using a similar method. It looks like you are using a 64bit JVM to run your program with, the Lego driver toolkit only works with 32bit JVMs.
