[OT] M1 Mac Mini USB problems

[Ralph DiMola]

I am having problems with my new 2020 Mac Mini's USB ports. The new time machine disk will only backup a gig or two before erroring out. Then the disk is then is not mountable. All sorts of errors when trying first aid or trying to mount it via first aid. Sent the disk back and the new one did the same thing. I can init it on the win 10 system and then the Mac Mini sees it again. I thought it was an unpowered USB-A hub issue. I then got the power supply for the hub and same thing. I bought an USB-C hub and again same thing. Plugged the Drive directly into the Mac Mini and same problems. My USB keyboard/mouse will not work reliably using either the USB-A or C hub. It seems that the Mac Mini's USB HW/SW is flakey. 

Has anyone else seen/heard anything like this?

This is very annoying after dropping over a yard and a half on this thing to replace my perfectly running Mac Book Pro so I could upgrade to Big Sur.
