USB C Can not power anything after update. Having usb powering issues with any device that consumes a little power: audio interfaces, usb mic's, all worked perfectly prior to updating to OS Ventura 13.1. Anyone else getting the warning? 'USB Accessories Disabled Unplug the accessory using too much power to re-enable USB devices' I have tried resetting the NVRAM, different cables, devices but anything that pulls even a little current will not work. Any help would be very much appreciated

How to enable powerchime on Big Sur when power cable disconnects By default, a power chime sounds when I plug in the power cable to my Macbook Pro. It is a nice thing to let me know when the machine is plugged in. But nothing similar happens when the power cable disconnects. Sometimes the power plug accidentally disconnects because I turned the computer around or move a little bit and I can not notice it if I am concentrated on other things or working on fullscreen. After a while, I realize the MacBook is running on battery and the battery is drained. This happens a lot and it unnecessarily ages the battery. Is there a way to make macOS play a sound when the power cable disconnects (like it does when the power cable is plugged in) or/and show a notification on the screen?
