I have trouble with an older video capture device. The windows 10 troubleshooter Wizard suggest the device is not compatible with usb 3.0 port.

Some people suggest a usb hub can make this device work, is this true?

What would make such a hub work? Which ones are likely to work? Powered or unpowered? Which chipset, brand, vendor, manufacturer has the best USB 2.0 emulation?

Some people suggest a usb hub can make this device work, is this true? What would make such a hub work?

In most generic form, the answer could be:

Modern PC systems have only xHCI USB 3.0 controller. The xHCI USB 3.0 controller has native support for USB 2.0 functionality. Older USB 2.0 handling over EHCI at root hub level is different form xHCI handling. Having a hub would force the system to load another part of USB stack, which uses more generic hub interface.

Or your "older video capture device" might have a sloppy-written driver that might be using some proprietary hooks to ECHI controller, which are not there for xHCI. That's why a generic hub might make a difference, resorting to more common generic interface.

Again, any particular problem with USB compatibility would require a deep debug effort using a good USB protocol analyzer, and/or careful examination of OS kernel messages. Generic answers are all speculations since you refuse to submit precise details of your system.

First of all, I don't think that this should be here, but here goes nothing..

I think "this" would help, but I don't think it's gonna work one way or another.

There should be another USB Port (Probably 2.0) that should work for the device.

I think you might be going about this the wrong way. USB2 devices should be compatible with USB3 ports/controlers: Are all USB-2 devices compatible with USB-3 port? BUT: it all depends on the implementation as others pointed out correctly (damn I took to long to write this answer! ;)

So you can try using a hub because it might "bypass" the implementation issue, but this will happen by "accident" (by chance) so there is no general advice that can be given for video capture devices. BUT: there might be a sure workaround for your specific device.

Update: In my experience powered hubs work better then unpowered and I usually have better results brands that give you the "most technical and most thorough" information on the product and give the best warranty. But then again, those are the most expensive ones. So if I would have to start a "solution guessing game" I would rather start with the cheapest option.
