I dont have data to back up that up, it is a "Just don't do it" thing with me.


I never had problems with my unpowered Anker 4 Port USB Hub. Only the ASI120MM needs power and that is also supplied by the RPI. But I want to add a WiFi USB stick and a USB SSD that doesn't work with a unpowered USB hub only.
My Mount is connected directly to a USB2 Port on the RPI

At the moment I have 3 cables that go up to the telescope. DSLR power, ZWO focuser and dew straps power (Y Cable) and my USB hub.

I don't need to supply the RPI with power via the USB hub, but if I can, why not?

I can also mount the powered USB hub directly on the telescope with a 3-way distributor for power, but then I would also have to mount the SSD on the telescope, which would mean additional weight. I'm pretty close to the photographic limit of my mount.
