same thing just started happening to me... i upgraded to monterey and my external hard drive keeps ejecting by itself!... please somebody knows any solutions for this? should i just go to apple store and talk about it? I need to fix this.

Man... I have same issue. My external hard disk is not read by the macbook... On the other hand my mouse through usb works perfectly. My kindle doesn´t get detected either. Please if you have a solution for this let me know. I would really appreciate it.

Yes we need a solution !!!
