Computer won't recognize my new Moto X4

[garybeckvt]

brand new Moto X4.

my desktop (PC) doesn't recognize it for file transfers. when i first plug the phone in to the computer, it is set to charge only. I change it to "transfer files" and nothing happens on the computer. the phone does not show up in the file manager as a device.

I tried it on another computer (Lenovo laptop) and it works correctly. the device shows up in the file manager and I can transfer files.

My old phone (Galaxy S5) still works fine on the PC. it is recognized and I can transfer files.

so the main problem seems to be my PC just doesn't like my new phone.

please help! I need to be able to transfer files from this computer to/from my new phone.

thanks!

Have you tried another port? Refreshing file manager?

Also try another usb lead. Make sure you are connected directly to the usb port and not through a hub or extension.

here's an update.
i have tried another computer and it works fine.
so there are now two computers that work and just one that doesn't.
i talked to Motorola and they had me try a few things:
-- I installed Motorola's Device Manager
-- I turned on developer mode and enabled USB debugging

still this one computer with Windows 8.1 doesn't recognize the phone

I only have one USB-C cord at this point so I cant try another cord. But I think it is pretty clear that my cord is good because it works with two other comptuers. One is Windows 7 and the other is Windows 10. the one that does not work is Windows 8.1.

any more ideas?

thanks!

Have you looked at the properties in windows device manager?
