Back in the days of Windows XP, when I plugged a USB 2.0 device into an non-USB 2.0 port I used to get a warning like:
This device can perform faster
This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port.

Now, I often accidentially plug my USB 3.0 storage devices into USB 2.0 ports and only notice when copying takes a long time. It would be nice to get a similar warning in this case, and according to a Google search, some people do get a warning message.
Just to be clear, I'm using Windows 10 (fully updated as of Jan. 2016). I have both USB 3.0 and USB 2.0 ports, Windows recognizes both as such. I tried a USB 3.0 stick/pendrive and an external hard drive, and I tried it on my laptop and my PC. In all cases, I get slow speed on the USB 2.0 ports and high speed on the USB 3.0 ports, but never a warning in the low speed case.
In the "Devices and Printers" window, when I select the USB 3.0 Drive, it actually says "This device can perform faster..." in the info area. What I'm looking for is the setting "Tell me if my device can perform faster" that used to be present in Windows 7, but it seems the GUI to toggle it has been removed. Is there any way to (re-) activate this warning?
