From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can a 10Gbps USB 3 host controller be configured to work at 5Gbps? (lemmy.ca)

Is that a thing at all? I doubt it but thought I'd check just in case.

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
