Thank you for your replies :) @mariushm: This example situation was more or less just to describe my question. I understand why I would get the slowdown and I am aware that I could solve it by using different USB controllers. But the idea was to pipe multiple USB2 devices through one USB3 cable. @Senzelian: Very interesting. So I'd need to look at "multi transaction translator" USB3 hubs. If they exist. Makes sense that having one TT creates an bottleneck. I guess you could imagine it as an USB2 hub that goes in the one TT and that goes in an USB3 hub, or something. Edit: Looks like you can find some if you do some research: https://www.ioiusb.com/Hub/U3H414E.htm also this TI chip looks like it would do the job: http://www.ti.com/product/TUSB8044A so I suspect there should be a few more hubs that use this or a similar chip to archive it. Thank you again @Senzelian for delivering the right keyword to search for.

Hi everyone, I just created an account to ask the following question here, but I have seen most of the LTT shows on YT (well, not the newer ones (last half year) and those that look too much like drama). Anyway, why I ask it here? This is a thing that might require someone to grab a few usb3 hubs and just test it (and maybe make a YT video about it when you run out of topics XD). Ok, so here is the question: Say I have an external USB2 HDD (read/write speed is limited by the USB2 protocol) and a USB2 webcam. Now I connect both to an USB2 hub and start my video stream while also accessing the HDD. the HDD access speed will be slowed down by my camera due to the shared USB2 connection between the hub and the PC. But what if I use an USB3 hub? Will both devices be able to run at full speed (only limited by the individual USB2 limitation)? Is that ensured for all USB3 hubs or are there some 'good' hubs that do that and some 'bad' ones that don't. Thanks for your help.
