Hello everyone.
I just received my freebox delta (after 8 months of waiting…) and thought I would put my Gladys instance on it. However, I just realized that you cannot use Bluetooth management as it is.
I wanted to know what the feedback / equipment used is for those who might be in my situation:
Thanks for your feedback 
For the USB hub part, it depends on what you want to connect to it. However, the Freebox Delta should provide enough power to power several power-hungry devices without too much of a problem, so there’s no need for an externally powered USB hub.
For my part, I use a very simple model that works very well.
Anker hub USB 3.0, 4 ports hub usb 3.0 alimenté, ultra fin pour MacBook, Mac Pro/mini, iMac, Surface Pro, XPS, Ordinateur Portable, clés USB, disques durs portables et bien plus encore : Amazon.fr: Informatique (10€)
Thanks lmilcent
For now, I would like to use a Bluetooth dongle (this is mainly the reference I need to get started) to go with the home automation VM and make Bluetooth presence work.
But I also have a Zigbee key that I would like to use later, and from what I quickly read about the Freebox, a powered USB hub was needed. I’ll keep your reference in mind anyway. 
hello everyone,
