That sounds like another of those, it's all very well following ideal practices, but it's going to break a ton of things that don't. And none of us are going to be in a place to contact their keyboard, drive, sound device, etc., manufacturer and get them to change their device to adhere to best practices. Nor can we get changes made to existing hardware. There's lots of things that just expect to be able to get max power from a port without doing anything to negotiate for it (be that resistors on the pins for hardware methods, or via software). I really question these power saving measures. I highly doubt that saving 200 mA on a USB port makes any significant difference, except to unexpected failures. Especially when you take into account the main grunt work of the PC using hundreds of watts. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
