Hi Leapers,
using the "DUET" software to use my ipad as secondary display for my laptop i get a "recogneized new
USB device message - do you want to transfer data from/to" each time I start the magic leap again. After that a "Duet Display connection - no installed apps" popup appears each time. Would be nice to get a button for "never ask this again for this USB device" 
Hi @pepone,
Thank you for bringing this to our attention. I understand how this can be frustrating to encounter every time you connect the device. I'll go ahead and give this feedback to our team and let them know about this desired feature.
It is possible to disable this in the developer settings as well. Settings > System > Developer > Disable USB detection dialog.
Best,
El
