Uploading/Linking Exception - UnsatisfiedLinkError

[mrasool]

Hi,

I am using Eclipse on Windows XP for testing and running a simple java program (R2MeToo.java) to upload in NXT Brick. I have configured all the environment variables and other stuff as specified, but when I click "leJOS Download", I see following:

Linking...
Uploading...

It looks like you have not got libusb installed on your PC. Are you trying to use usb or bluetooth to upload the program? If you are using Bluetooth you can specified the -b flag to the nxj or nxjupload to force it to use Bluetooth.

I am using USB to upload the code. How can I install libusb?

Thanks.
