USB problem/Thunderbolt on Mac mini M4

(USB mouse & keyboard) intermittent connection problems through various adaptors & cords:


Connected to the Apple USB-C to USB Adapter through the front USB-C ports - ok there.


But, on the back Thunderbolt ports, using my OWC Thunderbolt-to-USB-C adapter cord connected with a USB-C female-to-USB-A female adapter with either the mouse or keyboard does not hold a strong connection, sometimes not at all.


3 back ports and they're relatively useless to me right now. Any suggestions to make this Thunderbolt work?

Mac mini, macOS 15.1

I’ve having the very same problem with my newly purchased base-model M4 Mac Mini. My old Apple Extended Wired USB Keyboard simply won’t be recognized, or intermittently stops working (same with my old LogiTech USB wired mouse).

i’ve tried plugging them in independently, and switching out the third-party adapter to an Apple made more than the results are exactly the same. Never, ever had any issues with this keyboard and mouse with any other Mac I’ve owned.
