Both USB 3 ports wont work simultaneously

Question

Hi ,

I recently purchased surface book. I was using mouse-without borders so I have connected my USB  Bluetooth receiver to the surface book so i can connect a wireless keyboard and mouse and it works. Now i wanted to connect  Ethernet so I  purchased USB 3 to Ethernet adapter from Microsoft. It works but now my wireless mouse wont.

It only works if i remove the USB to Ethernet adapter from other USB port, it's super annoying to know that only 1 USB 3 port will work at a time?

It doesn't make sense!!!

Please help me out here.

Answer 1

Question.. why use an external Bluetooth dongle? Your surface has bluetooth built in. Is this an issue where the program won't work with the internal connection?

Answer 2

I have Logitech Wireless keyboard and Mouse, the USB3 dongle( Bluetooth receiver) came with them . So I am using that to use my keyboard and mouse .

The problem is is I disconnect the USB3 to enternet adepter , My wireless keyboard and mouse works.

If I connect both USB3 devices ( 1 with USB3 Ethernet adaptor and another ESB wireless receiver) only Ethernet works?

Answer 3

Have you tried pairing the Logitech gear with the internal Bluetooth? Are you sure it is Bluetooth? Can you please try?

Answer 4

I just checked Logitech's website and found that the USB dongle works on 2.4 GHz Wi-Fi  not Bluetooth. So connecting these wireless mouse and keyboard from Surface book's internal Bluetooth out of question here .

So my problem still persists that only one USB3 port works at a time not both same time?

Answer 5

Ok, there is sometimes a conflict between 2.4GHz devices and USB 3.0. and usually we see it with 2.4GHz WiFi. This is likely your issue. see https://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html there may not be a good solution to this one.
