Could you confirm that you have a /dev/ttyUSB0 device available?
And that is the _only_ output you see? If so, that's quite surprising...
I've never seen the sicklms node output so little before when it cannot
connect to a SICK (even when I, say, don't have a USB adapter plugged in).

Can you try killing and restarting the sicklms node after the SICK's light
turns green? Are you certain that you and your colleague are using the exact
same settings and parameters to the sicklms node? Also, can you try
different USB ports on your computer (I've seen USB->Serial adapters be
unusable on say, USB 3.0 ports of certain motherboards)?
