Can a 10Gbps USB 3 host controller be configured to work at 5Gbps?
Can a 10Gbps USB 3 host controller be configured to work at 5Gbps?
Is that a thing at all? I doubt it but thought I'd check just in case.
Sounds like a case of X-Y problem
It'll be compatible with 5 Gbps devices, but if you're intentionally looking to restrict even 10 Gbps devices down to 5 Gbps for some reason, you might be able to find something in your BIOS that lets you do that, or you can get a USB 3.0 extension cable that'll limit your speeds to 5 Gbps.
The extension cable is a great idea. I'm currently trying 5Gb hubs on the path. Seems to work.
E: I think the USB-A connector for 5Gb and 10Gb is the same. The 10Gb cable must simply carry double the rate without losing data due to noise. Similar to Cat 5 vs Cat 6 ethernet cables. If so an extension should keep the controller-advertised speed downstream. Seems like hubs are the only option.
There are powered extensions, so one of those might work, but a hub is certainly a comparable price and a more compact solution
Assuming you have a free PCIe slot, maybe just buy a PCIe USB card to use instead of what seems to be a faulty AMD USB controller.
Already done. I'm just trying to exhaust all the hypotheses I have in case I stumble upon a durable workaround that is applicable for others and cheaper. Good USB add-in cards are not cheap.
It will use whatever connection speed the device connected supports up to the speed of the host interface
What kind of controller and what kind of Gb are you talking about?
Storage controller for USB sticks?
Or gaming controller with an advertised Gb/s USB bandwidth?
