USB devices disconnect after sleep, have to unplug/replug every single time

Hello,

This pertains to pretty much all USB devices connected to my M1 MacBook Air, but in particularly is my Motu M4 audio interface and a USB external SSD. These devices are connected to the MacBook Air with a USBC to USB cable. Every time the computer goes to sleep I and I wake it up, my audio device and the SSD are no longer recognized. I get hard drive eject warnings and I have no audio. I have to physically unplug and replug the devices in order for the computer to recognize them again. This is super frustrating. Is there a fix?

MacBook Air (2020 or later)

TXBDan,

Thank you for the information you have provided so far, have you tried starting your computer in Safe Mode, if not here is how: Start up your Mac in safe mode.

Starting up your Mac in Safe Mode can help determine whether issues you’re experiencing are caused by software that loads as your Mac starts up.

Take Care!

Thanks, but that doesn't help. This problem seems unique to either this M1 MBA or Big Sur. I've had many Macs in the past with similar equipment and never had this problem.
