How to test USB Hub speed?

colhany , 06-17-2023, 11:44 AM
I'm designing a USB SS Hub, my question is, how do I test that my design can actually reach 5Gbps after manufacturing? Knowing that I don't have any USB device that reaches those speeds to test it with.

Do you want the cheap solution or the correct one?
The correct one: https://usb.org/compliance
The cheap one: keep your fingers crossed and test with devices you have.
Or something in between: https://www.youtube.com/watch?v=o8DPlqWVmzk

It seems I'll go with the cheap one, seeing as I don't have enough money for the correct one or a 13GHz oscilloscope laying around
Thank you

I agree with @qdrives
- The proper way is to run USB compliance test, this may help: https://youtu.be/q6fhmTL-Sgo
- The usual (cheap) way is to buy different usb devices with maximum possible speed and test them.

@robertferanec I knew you had a video about it, but google did not come up with it. Perhaps because I was mentioning USB3...
