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.
You're viewing a single thread.
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
It does not have to be compatible. The Ethernet 5 Gbps and 2.5 Gbps standards are newer the 10 Gbps. So there are controllers that only support 10 Gbps links and not 5 and 2.5.
This is about USB
Thanks my bad. OP was talking about ethernet in some of his comments so i somehow thought it was about an USB connected NIC.
