USB Sharing Switch Safety Concern

[Fenris_Wolf]

I am not sure how forums work as I have never posted on one before, but I really needed advice on this. I recently bought a USB sharing switch by Sabrent (1 peripheral port + 2 pc ports (usb3.0)), and I am very happy with it. One concern I had was over some comments regarding it that I saw about it making peoples’ devices stop working and sone stuff about overvoltage. I assumed at the time that it would not be a problem as they were only a few who complained. My atolla USB hub that I have used for a very long time is now connected to this sharing switch, but for some reason ports on it that should not be on are lighting up, and when I unplug it from the sharing switch and use it independently, it works fine. I was wondering if this is a safety hazard and/or if there is a device I can use to monitor the voltage as I use it without inhibiting performance or a device I can use to stay safe. Let me know if I posted this in the wrong section... thanks!
