Audio stops with the new firmware

If i use rekorbox dj connected in hid to my cdj 2000 nexs2 connected with usb everything is perfect,
If i connect a usb stick and obviously try to switch to usb
Into the cd that is not playing all the rekordbox freeze for 5 seconds and stop the audio. This happens from i update the cd to the new firmware 1.40 with the old one i can switch to usb and use sticks without problem. I don't use hub just 2 cables in 2 usb ports. It's a problem because i'm djing with rekordbox dj and the other dj in the club use usb sticks and we can't switch without stopping the audio. Why all stop if i'm not using that cd to play? Can i downgrade to 1.31 the nxs2 ??? Let me know. I have all update to the new stuff osx, rekordbox and the cdjs. Help me

I just tried with a pair of CDJ2000NXS2's at firmware 1.10 and it does indeed disconnect and in the process, interrupts the audio playback on the OTHER device, and here's why... rekordbox is playing through a set configuration of audio devices (for Mac, an aggregate, for PC, a combined driver), when you disconnect the USB from one of the players, that configuration changes and the application using that audio device recognizes the change, disconnects and reconnects the audio device.

My recommendation is as follows:

When switching DJs, the second DJ should load a USB device into one of the players, mixing out of the first DJ's track. ONLY once the CDJ with the USB device is playing from that source should both USB cables be swapped from DJ one to DJ two.

The problem is only with the 1.40 firmware but i can't downgrade, with the 1.31
Everything was perfect

Somehow I doubt it, but I'll see if I can upgrade mine to 1.31 to test and let you know what I find.

Which OS are you running?

I got one of the engineers to send me 1.310 and it did the exact same thing when one CDJ's USB was disconnected under Windows 8.1; a few seconds of hiccup then audio resumed.

I booted into OS X 10.11, created an aggregate device for the two CDJs, configured rekordbox for the aggregate, got music playing through both, unplugged one USB and poof. Died completely.

So unless you can provide a bit more information as to the circumstances under which you're having this work properly, I'm standing by my previous statement of "somehow, I doubt it."

The last one, but i'm not talking about to disconnet the usb cables from the cdplayers , but just to switch from link to usb the browser of music. When rekordbox is playing if you switch it freeze for 5 seconds.
