Usb 3.0 Ports Work Differently

Windows 10 Pro (up to date), Z97 MB, i7-4790K CPU, 32MB Ram. Non-gaming environment.
Strange issue. When using a USB microphone and an audio editing/recording app I get different gain signals when plugged into different USB 3.0 ports. The case is a Rosewill CHALLENGER Black ATX Mid Tower Computer Case. On the front panel of the case at the top is a USB 3.0 ports and 2 USB 2.0 ports. When I plug the mic into the USB3.0 / 2.0 ports the gain signal is very strong and shows up nicely on the app recording screen. However, the 2.0 ports are very loose and won't stay connected, so I only use the 3.0 port.

I also have a Rosewill USB 3.0 / 4 port / pcie card. When plugging the mic into those 4 ports OR into the motherboard 3.0 ports the recording app gain signal drops to nearly indistinguishable.

What could be causing this? Can this be remedied? If so, how?

Thanks for helping,
Dekade

 

Hard to tell what is happening but I note many motherboards have multiple USB hubs servicing the various pairs of ports. So it may have something to do with that.

 

Hmm. This is a tough one.
