You say older hardware so just curious if you happen to have an Asus mobo? If we are talking AM4 era, heads up that Asus mobos saw a lot of firmware revisions in 2025 including patches for usb-related issues. I have a b550 board that has been troublesome but seems a bit more stable with the latest firmware.

I stocked up on rk3566/rk3588 boards during the pandemic. They make excellent little network appliances or light-duty workstations. Mainline kernel support is now solid for both chipsets.
