USB 3.1 GEN 2 devices, connected to Thunderbolt 3 ports

if I connect, let’s say, a Samsung T5 (usb 3.1 gen 2 device) to a thunderbolt 3 port, will there still be transfer rate up to 40gbps? Also, if so, will I have to use thunderbolt 3 cable?

usb 3.1 storage device to a thunderbolt 2 input Is there some convoluted way to hookup a usb 3.1 device to a thunderbolt 2 input? I have a late 2014 mini with usb 3.0 and thunderbolt 2. USB 3.1 provides faster transfer rate than 3.0 so I figure if I can utilize the thunderbolt input of the mini with a USB 3.1 device I might take advantage of the faster rate. I figure I'd at least need something to convert the plug but I'm guessing I might need else. So maybe if I find a USB 3.1 multiport device with a thunderbolt? I'd be happy if I could find a reasonably priced high capacity thunderbolt storage device but thats not going to happen. Thanks john

Thunderbolt ports or any other type of ports cant speed up devices made with other protocols like usb3.1 or usb2 or lower

Great! Thanks rudegar

Reason being, a device can only pull as much power required by its protocol allows, and can’t receive the 100w from TB3 port. In turn, slower speeds, correct?
