HELP! CDJ 3000 don't see the pen drive on source HELP!

CDJ 3000 don't see the pen drive on source, look the number of the link is on but don't see the pen drive

1 - firmware is update with 3.11

2 - I have already tested another network cable

3 - I connected other CDJs and only this CDJ does not read the other pen drives, and the other CDJs cannot read the pen drive that is on it

4 - notice that the cdj link number is apparently working, but it doesn't work
