<p>I tried to do the measures without the strontium source, but the Alibava didn't cooperate with me.</p>
<p>First, it wasn't catching any events, then, I tried to put the Trigger on -20 and on -10. Nothing either..</p>
<p>Second, when I tried to restart the Alibava, it didn't open anymore. I used the comand sudo chmod a+rw/dev/ttyUSB0 and didn't work..</p>
<p>This message appeared: chmod: missing operand after ‘a+rw/dev/ttyUSB0’<br />
Try 'chmod --help' for more information.<br />
Then, I give up. <br />

<p> the command is wrong. it told you: missing operand. it means it misses an argument</p>
<p>you miss a space:</p>
<p>sudo chmod a+rw /dev/ttyUSB0</p>
<p> </p>
<p>copy and paste the command above.</p> |
