bosun21 Posted December 23, 2022 Posted December 23, 2022 Why don’t ZWO and other camera manufacturers not fit an additional usb2 port on their uncooled cameras? I decided to try EEVA and AP to see whether I have a future with this branch of astronomy. I have run out of USB ports on my asiair plus and can’t connect my new electronic filter wheel and also had to unplug my 256GB memory stick. I am using the four ports with my ASI585 MC, my ASI120MM guide camera, my mount and my EAF. This try out has been expensive to say the least and now I have to find at least £1K for a cooled camera. Why don’t they fit at least one on their uncooled cameras. It’s maddening and expensive to say the least.
Starflyer Posted December 23, 2022 Posted December 23, 2022 (edited) Use a proper, separate, USB hub if you can. The USB hubs built into ZWO cameras are notoriously flaky, it'd be an even more expensive try out if you bought a new camera only to find it hasn't solved your problem.

Sadly you need to be careful when buying dedicated USB hubs too. I bought one from a local shop, USB3. And my RisingCam 571 complained about it only having a 2.0 connection, and did not work as a result. I ordered a Pegasus box on 31october... Still not here yet but flo said their expected delivery was in "early december". I guess Pegasus are struggling for volume. 1

How can my asiair plus control my electronic focuser via a hub?

I recently got a Pegasus box, and it’s working perfectly with two USB3 IMX571 cameras attached so you won’t be disappointed 👍🏼 10 hours ago, Starflyer said: The USB hubs built into ZWO cameras are notoriously flaky I use my ZWO camera to run an OAG via the usb rear ports, hasn’t given me any trouble in almost 2 years. It’s the one feature I miss not being present on the QHY equivalent. 1
PeterC65 Posted December 24, 2022 Posted December 24, 2022 You should be able to split any one of your Asiair Plus USB ports into multiple ports using a hub. The software should just see the additional devices transparently. A hub will be much less expensive than a cooled camera upgrade, and you really don't need a cooled camera for EEVA. I use this USB 3.0 hub (I bought mine from Amazon). It seems to work well and is much cheaper that the Pegasus Hub. What I like about it is that it's long and thin and so straps nicely out of the way to a tripod leg, and it can be powered locally from 12V, so directly from the mount battery (most USB hubs need 5V). It does also work without a local power supply. 1
