DVR17 Studio - Dongle not detected [solved]

I just got my dongle for Studio. Installed the studio version, plugged the dongle and ... nothing. It asks for an activation code

lsusb shows the dongle being detected :

Bus 003 Device 017: ID 096e:0201 Feitian Technologies, Inc. USB DONGLE

The logs show this which might be relevant ?

[0x7fecf31f4680] | LeManager | ERROR | 2021-02-26 14:39:23,422 | 22, 174, -1

(I was running the 17b9 free version just fine)

Ok ... I was a bit fast on the trigger to ask here.

Simple check with strace shows it's a permission issue with the binary not able to talk to the dongle because of missing udev rules. Fixed permissions and now Studio starts
