Windows 10: Help with connecting Logitech M570 mouse with MS Surface Pro 6?

I have an HP750 and a MS Surface Pro 6, both with latest Windows 10, and I'm using two Logitech mice, M570 and M720, along with a unifying USB (from the 720) connected to the Surface. I'm also using Options between the two computers; and obviously, only can use the 720 for this function. All drivers are up to date. The 720 works on both computers, but the 570 only works just on the HP and I can't get it to connect to the Surface. I have tried connecting the 570 to the Surface via bluetooth and via wireless (have swapped the 570's unifying usb to the Surface-didn't work,) but the Surface just never recognized the 570...although the 720 is recognized. My goal is to be able to get the 570 to work on both computers as does the 570. Thanks.

How do I make my Logitech M570 mouse and K350 Keyboard defaults?

My MS office 2016 defaults to MS mouse/keyboard even if not connected. How do I set my Logitech M570 and K350 as default devices?

 

Logitech M570 Trackball Wireless Mouse Right Clicking?

I have several M570's on the go here, and other Logitech keyboards etc that all use the Unifying reciever. I don't install the Logitech software. I do sometimes install just the Unifying utility if I have to link or unlink a device to the dongle. All my Logitech stuff works with the basic Windows 10 drivers. The only things that don't work are those Blue special keys on my Keyboards.
I have had the micro switches go bad on my M570's from time to time. Mostly because I play FPS games with my M570. I just bought an inexpensive Logitech mouse and robbed it of its click switches. Then replace the bad one in my M570 with the good one from the mouse. I'm a retired electronic technician so its not a big deal for me to do that. Saves me buying another M570. I think I've replaced one button in each of the two I own. I get multi clciks when they go bad. I press the mouse button once and get a double click etc. I don't remeber it clicking all on its own though. Or sticking on (clicked).

 

Getting Logitech M570 to function with Logitech Options?


I originally posted this problem (One Logitech Setpoint for two different Logitech mice? - Windows 10 Forums), but as I feel there's a new twist, it would be best to start a new thread.

Both my mice (M570 and M720) have the Logitech unifying mark on them, and there is a Logitech unifying dongle in place that was first being used by M570 with Setpoint. However, I found that Setpoint wouldn't recognize my new mouse (M720.) I then found Logitech's Options program (Logitech Options - Logitech Support) that offered more than Setpoint. DL'd Options, but it initially only recognized M720 and not M570. Using Options "add device," I kept getting "Try again" and haven't been able to get M570 to function on Options. No matter what I do, when Options is open, it only shows M720. Although M570 does function as setup on setpoint, I can't get to use setups for individual programs using Options??? All firmware is uptaded.
