USB device not shown in drive/folder window

[roycheers]

After updating to the latest version 26..70.0500 when I plug a USB stick into a USB port it is not displayed. If I open 'Disk Management' all the USB ports are listed, and if I open Windows Explorer I can see and access the USB stick.
I am using Windows 10. I am not using the Mini tree.
Please advise.

I meant 'Device Manager' not 'Disk Management', of course

Does it have a drive letter?

Yes it does.
I was used to finding it low down on the list of drives, but now it is showing higher in the drive/folder list.
Problem solved. Thanks for your help.
