Wireless adapter doesn't work plugged into MM1000 use port

Hello,

I have the MM1000 mouse pad with the Dark Core RGB SE mouse, and it is recommended to use the USB passthrough port on the MM1000 mousepad to help maximize performance by reducing latency and stronger signal. For some reason that the the only USB port that I can find on my computer that it won't work on. It's almost like ti doesn't even port up the dongle at all. I have tested the USB port on the mousepad and it does work well on other times. Is there a reason that the adapter wouldn't work in the M1000 mouse pad? I have all firmware and everything updated. And is plugged into 2 USB 3.0 ports.
