But it fails when I try to upload:

java.io.IOException: Error in write
See Eclipse error log for detailed stack trace.
it hangs at "Found NXT: GRB 0016531192BF" until the nxt automatically turns off, at which point it throws the IOException. Other members of my team are using the exact same setup as me and encounter no problems, so the only thing I can think of is that they previously installed some package that I did not or my computer is physically incapable for some reason.
