First disconnect the disk; next run lsblk >lsblk.old, next connect the
disk, next run lsblk >lsblk.new.  Finally do a diff on lsblk.old lsblk.new
and see if something shows up in lsblk.new that isn't in lsblk.old.

easier, diff -aq lsblk.old lsblk.new
Even without that, wc -l lsblk.old && wc -l lsblk.new
With two different numbers, the new drive is recognized.

Can I do a diff using the following command in a terminal?

diff -c lsblk.old lsblk.new

Have an iso for which you know its size.
Use dd to copy that iso onto a usb 2.0 drive and time the copy.
Copy that same iso onto the usb 3.0 drive and time it.
If the usb 3.0 copy takes less time in the neighborhood of the expected
speed difference of usb 3.0 to usb 2.0 then you got fortunate.
If the copy takes the same amount of time or nearly the same amount of
time then usb 3.0 is not being used.
This is best done using a sports watch or stop watch.

You can install hwinfo and it will tell you what's installed in your
computer, including the type of usb controler.

Or you can simply check the specs of your computer.

Have you tried, also you already have another answer regarding looking
into your logs. This will tell you if your drive is using USB 3 or not.
Also, some computer have only some port USB 3, the other will be only
USB 2. So looking at the logs will make sure you connected to the good port.

What have you tried before asking for help ? This sound to me like we
already gave you all the good options to know what's going on. What are
you expecting more ?

This sounds much to me like "I want to know if my computer is USB 3 but
I didn't even google-it"...

Calling people who try to help you "foolish" is not nice
(and might end up in nobody wanting to help you).

What is foolish is not to even check in the specifications of one's
computer if it does support USB 3.0 at the hardware level.

There's a trick called "help yourself and we'll help you", this can also
be called "do your part".

Using lsusb you can see on what bus your devices in plugged into. As
computers often have some port only USB 2.0 and some supporting USB 2.0
and 3.0, this way you can make sure your device is plugged into the 3.0
ones.

How to know what port support what type of USB ?

hwinfo --usb-ctrl

And after doing

lsusb -t

Now be easy on others, will you?

Sometimes I send out a help request to immediately slap my forehead:
the answer was written on the package ;-)

Well maybe you forgot a basic rule of life, not only computing.
You are responsible for your own success. Before asking for help, do
something to find a solution yourself.

Oh, no, too complicated to look on packages.debian.org so I'll ask on
the mailing list what's the latest version of package xyz and if it's
available in backports.

Oh, no, too complicated to do a man dd to know what are the command line
options. I'll just ask on the mailing list...

If you don't bother making little effort then people won't make them
either. So when you ask question, it will just be "Oh this guy always
ask dumb question, now he asked a good question but if he ask so simple
question most of the time, this mean I'll have to explain everything to
him. If a he doesn't know what this word mean then I'll need to explain
it too, because he won't even take the time to check what it means. He's
just gonna ask me back what's a "canarie" or what's the "stack" when we
are talking about buffer overflow.

Do I really want to get into all this ? No...
So I won't answer and you loose your chance to get real help when it's
for something that you won't find easily the answer...

While I mostly agree with your point, I believe it can be done better, 
nicer, and ultimately more helpful.

Since you've been pointing people to ESR's writings, allow me to suggest 
you (re)read the section entitled "How to Answer Questions in a Helpful 
Way", from his famous "How To Ask Questions The Smart Way" essay[1].

http://www.catb.org/esr/faqs/smart-questions.html#idm667

[1] which I believe is at least slightly outdated in regards to 
communication style in general.

Kind regards,
Andrei

I've said what I think is the closest to the truth.
Now if someone don't like the hint I gave him, he can simply ignore what
I write, the same way I'll ignore most questions that seem much like RTFM.

It seems to be this type of thinking that sound like "Why read a book
when I can ask question". Exactly.... Why be smart and understand how
things work (so I don't have to ask questions) when I can simply learn
how to repeat like a parrot.

Thanks.  I wasn't familiar with the `-t` arg to `lsusb`, it's
very informative (e.g. it gives you the actual speed negotiated, so
I can see that my USB C phone still uses 480Mb/s)

Maybe you shall read this one.

Will give you a hand for next time.

And don't forget, this ain't microsoft tech support.

No ones has obligation to help you out. If you don't like what people
suggest you, at least explain why the solution doesn't seem to fit.
Solutions are useless unless you have content to back the choices you've
done. Without explanation, they are like politics, pure opinion and a
smell of astrology.

I'm sure it wasn't intentional. I just pointed it out because I sometimes
do myself such things and am happy when others tell me.

You should see something in your logs, this is what I get for a usb 3.1 device:

kernel: usb 2-1.2: new SuperSpeed Gen 1 USB device number 5 using xhci_hcd

USB 2 is only "high-speed":

kernel: usb 1-1.3: new high-speed USB device number 12 using xhci_hcd

What did the message you got says ?

Let me copy here :

==START==
You should see something in your logs, this is what I get for a usb 3.1
device:

kernel: usb 2-1.2: new SuperSpeed Gen 1 USB device number 5 using xhci_hcd

USB 2 is only "high-speed":

kernel: usb 1-1.3: new high-speed USB device number 12 using xhci_hcd

Regards,
Geoff
==STOP==

Now look at the 1st line of the logs you copied...
You need more help ?

Give you a hint : USB 2 is only "high-speed"

Definitely looks like usb 2, the ehci driver also points to this. Is the interface on the PC usb 3?

What kernel are you running, mine seems to use the xhci driver even for usb 2.
