XDJ -RR E-8307 divice no response

Good Afternoon,

i just reformatted my usb 2 times and again copied a copy of my old usb including the hidden folders and transferred it to my new usb scandisk extreme pro 3.2 but this problem persists. while my old usb just works on my XDJ-RR could someone tell me what else I can do version of the XDJ-RR is 1.03 at the moment.

Best regards,
