Problem with LeJOS on MacBook/WinXP

Postby williammarsh » Sat Sep 08, 2007 9:24 pm


I am trying to install lejos on a MacBook running WinXP SP2 using Bootcamp (i.e. the Apple supplied drivers for Win on MacBooks).

LibUSB-Win32 1.12.1 gives me a problem: it seems to install ok (and the test program works) but after it is installed the machine crashes on start-up and has to be brought back to life with the 'Restore last working configuration option'. This removes some part of the LibUSB installation, so that the test program stops working. I tried the installation twice; the second time installing in a directory with no spaces (c:\LibUSB). The result is the same.

I tried running nxjflash but it is unable to find the NXT. I also tried nxjbrowse: it sees the NXT bluetooth but is unable to communicate.

Using the Lego supplied software I am able to communication with the NXT using both USB and Bluetooth.

Some questions:

1. Has anyone encountered this problem using a MacBook/WinXP or successfully installed leJOS on MacBook/WinXP.

2. If I use another computer to flash the leJOS firmware to my NXT, will I be able to use the bluetooth interface on the machine without libUSB installed.

I'd be grateful for any help with this.

Yes, if you do the nxjflash on another machine, you should be able to use the leJOS tools over Bluetooth on the machine without libusb.

Use the -b flag to force it to use Bluetooth, or it will look for the NXT on USB first.
