I'm copying files to a USB 3.0 stick. The USB stick is plugged to a blue USB port.
I'm copying 22 files of 1.5GB.
When I do the copy (simple drag and drop), the copy dialog reports a speed of ~60MB/s, then, after copying the first 1.5 GB (surely the first file), progression stops for several minutes and after that, transfer speed is reported to be less than 3MB/s. The original transfer time estimated to a few minutes is now estimated to few hours...

The device is on Bus 01, reported 480M, is that a speed? If so, I see Bus 02 has a higher rate of 5000M, but I tried all ports accessible and I could not have the USB stick appear under this Bus.

- Same files are copied in less than an hour using the same USB stick on a Windows computer, takes more than 6 hours using my Linux machine. So I really suspect the Linux system does not handle USB 3 correctly (as it shows the key as 480M, while it IS a USB 3 memory stick: has a blue USB connector and is sold as USB 3)
- Tried a different USB 3 stick. It appears under Bus 02 5000M this time and copy is much faster (even if estimation remains hazardous). So apparently my computer can handle some USB 3 devices correctly but not the one I'm using in my original post. As apparently Windows is able to it, hopefully there is something that can be done for Linux to manage it a better way.
How can I make the copy faster?
