What even is USB 3.1 Gen 4 ?

Hi Rob
If you enter “USB 3.1 Gen 4” into your browser Google comes up with 75,700,000 results. Must be something useful there.

Thanks for the snide reply. But searching for “USB 3.1 Gen 4” only nets 2,070,000 results for me, and they’re all either product pages for this cable from Adafruit (the brand of this product), this page itself or from other sellers. But if you actually look further, you’ll see no such specification exists. The Wikipedia page for the USB 3 spec curiously is absent of any such definition, so is the authoritative source USB-IF. So my question remains completely valid.

Hi Robert,

Talking about the number google spits out isn’t too helpful, as generally only the first or second pages are of use, in this case, many of them point back to this site. It’s assumed people can google things.

On possibly the biggest technical Q&A site on the web, Stack Overflow, they’ve had a number of discussions on this:

Just food for thought, your technical know-how is always appreciated here :slight_smile:

Hi Rob, welcome back!

As you found, Adafruit distributes this product. They actually have a guide on USB versions, and acknowledge the confusion, I think mentioning that they believe Gen 4 should read Gen 2:

Not sure why they haven’t fixed that up, but you should be able to just assume they mean 2.

Hi Rob, James
Was not meant to be a “snide” reply. Just pointing out that I and many others would have to do this if they were to attempt to answer your query and is something that you (and quite a few others) could do in the first instance. If that fails or is unclear (as is often the case) the Forum is a good place to reach out. There are often individuals who happen to be the full bottle on things of this nature.

As this Forum is basically a learning centre I firmly believe in knowing how and just as importantly where to look is a fundamental part of the learning curve. There is so much rapidly changing information out there it is imperative that one has a grasp on how and where to look. For instance I have found Element 14 a good source for data sheets. It is for this reason I usually encourage some self research in the quest for answers.

I agree that it is usually only the first couple of pages of Google that are the most use but on the odd (read very odd) occasion I have found what I was looking for further down in the murk.
Cheers Bob
