Today is not the day for astrophotography for me, but for the heck of it (and having a 20 minute window of clear skies) I experimented with connections.
Whether it's known for some or not, when it comes to my QHY183C, there is this religous routine I have to go through, and that is, if I connect it to a software (N.I.N.A or Sharpcap) I have to go to the mount, unplug the USB and plug it back, otherwise I won't get any images.
Same thing if I switch between software, like I'm doing a Bathinov mask with sharpcap, then I disconnect the camera within the software, and then let's say I start N.I.N.A and connect the camera - again- I have to go to the mount unplug/replug the camera again from the usb hub or from the back of the camera.
I tried this with many USB 3.0 cables and 2 different drivers over the past 8 months , even on different computers and different setups, it's always the same routine- basically it's not my equipment's problem.
So, today I also have another QHY camera, which a color planetary/ guider. QHY5III224. This camera also have a USB 3.0 connection.
So instead of the USB 3.0 wires, I connected both with USB 2.0 to the hub.
Interestingly, I don't have to do my routine of disconnecting/reconnecting , not even the 183. They just work fine with USB 2.0, actually feel more stable I even quick-switched them in Sharpcap and nothing. Works right off the bet, no plugging/unplugging required.
I have to add, they aren't even the best USB 2.0 cables around, they are flat and look quite thin. They come packaged with a ZWO guide camera.
I also tried how far I can push the camera and I had 20fps as max pointed at Jupiter. I'm not using these cameras for planetary video/photo, I DSO image with them and the smaller camera is for guiding, so the shortest exposure I have to take are no less than 1 second.
So just a heads up for anyone having connection issues. Try a USB 2.0 cable they fit right in the USB 3.0 port.
