I have had those active extensions for a while and they work well. I have two chained up to 10m.
Recently I've been having a few weird issues that didn't make sense at all. The hitech astro hub would connect but I couldn't switch the power to the ports on/off via the PC software. The QHY9 would connect but the picture wouldn't download via the USB line. I'd only get a black picture. And a few other things that didn't make much sense. As if it was working but not all of it. Weid.
Anyway I found out what the problen could be. I swapped the two active cable orders. I have on that has a ferrite block on it and that the one I keep closest to the laptop, the other length runs to the mount.
If I have them in this order ll works well. If I swap them then I have the same issues. Has anybody experienced the same thing with these extensions?
Does this make any sense that the order they're plugged in influence any of the software or has any effect with the drivers?
