Wireless Mouse stops working when external HDD plugged in to USB3 port

I have a minor but annoying problem and can't find a solution....

My wireless mouse stops working when an external USB3 HDD is plugged in to USB3 port. The mouse is about 3 feet away from the receiver.

My mouse is a Logitech M310.

• I don't have the problem if a USB 2 external HDD is connected to either a USB2 or USB3 port.
• I have moved the mouse receiver to different ports on both the front and back of the computer but this doesn't change anything.
• If I move the mouse very close to the receiver (a couple of inches), it works so it seems that the wireless range is reduced when the USB3 HDD is plugged in.
• If I connect a wired mouse, it works fine.
• I have 2 USB3 ports and the problem is the same on both.
• If the USB3 HDD is connected to a USB2 port, the mouse works normally.
• I changed the battery in the mouse but this didn't help.
• the USB3 HDD is a WD Passport that is self powered through the USB port.

Any suggestions?

Have you got a friend's computer you could run a test on.

I would take mouse, dongle and external drive and test. This would eliminate your rig and point to some defect with the external drive.
