Power off USB ports during sleep

[Flyview]

Hi everyone!

Is there a way to power down the USB ports during sleep? They seem to only power down during standby (hibernation) which can come many hours later. I have a laptop cooler/stand I put my laptop on. I'd like the fans to turn off when I close the lid and the computer goes to sleep.

This is on a late 2013 15" MBP running Sonoma.

Thanks!

One solution I've found is to set hibernatemode to 25. This skips sleep and goes straight into hibernate (standby), for which USB ports are not powered. This is not ideal because waking from standby is way slower. Is there anything else we can come up with?

How about something like this?

Cable Matters 5Gbps USB 3.0 Extension Cable with On Off Switch with Data 6 ft, Support Both Data and Power (USB 3.0 On Off Switch/USB On Off Switch)

Cable Matters Short USB 3.0 Extension Cable (USB 3.0 Extender Cable) with On Off Switch in 6 ft

No, it's not "a software solution".
But it WILL WORK if you don't mind physically "flipping the switch".

There are others that are available.
Perhaps one with a shorter cable.
