The USB Hub is 2. I have only used USB 2.
I have tried the powered Hub I had earlier but it does not work at all now. Which is why I got a replacement. I have also tried several cables.
The 4 socket non-powered Hub which I have had for years works perfectly (establishing that the USB drives are not faulty) EXCEPT for one thing, driving the external USB DVD / CD Reader / Writer, which I got for my 2-in-1 Tablet, as it does not have its own DVD drive. So it would now seem I have two non-functioning powered Hubs, an older one and a new one. I got the latter via Ebay from China, because I liked the space-saving design but it was so cheap it will not be worth returning. I have seen the same / similar sold by a UK firm for about twice the price (but still cheap) and have in mind to try again. I have emailed them to describe the situation and confirm their returns policy. I believe I could return the other one to China, but the shipping cost would be greater than the value.
It was mainly the error reports which mystified me and seemed to suggest the USB Flash drives were at fault but now I do not think they are.
