Just stumbled over an article in ct 12/2017 Page 162 (german computer magazin). It says, USB3 can intereference with devices like 2.4Ghz WLAN, USB-receivers.
References: White-Paper Intel: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html Asus-FAQ: https://www.asus.com/de/support/faq/1004004/ So maybe the wohle thing is "hardware"-related and no SW-issue... Furthermore, I didn't have the error for a long time now. When I experienced it, I had external USB3-drive with a short cable connected. It seems to be depending further on the exact hardware, the cable it's using and the position of the devices involved.
