我有一个 Mindstorms NXT，只能用 sudo 刷新它，对吗？所以现在我想上传一个测试程序，但是：
Initializing LeJOS JDK at /opt/lukas/lejos
Linking ...
Program has been linked successfully
Uploading ...
leJOS NXJ> Failed to find any NXTs
leJOS NXJ> Failed to connect to any NXT
No NXT found - is it switched on and plugged in (for USB)?
uploading the program failed with exit status 1
我使用 eclipse 和 eclipse 插件。NXT 已开启并通过 USB 连接，我认为存在一些权限问题。你有什么想法？
