I took's watari's advise and connected my keyboard mouse usb hub to the front and my Acasis SSD at the back port... so far the acasis only disconnected once when the unit went to sleep, got the drive disconnected without safely removal warning upon login...

I think my mouse's disconnection mainly due to the razer macos app did not function after relogin. Disabled the app's sleeping feature and set it to auto start on every login seem to have solved my problem too....

Anyone else using razer peripherals on their Mini M4?

Because i used the app to switch on and off the RGB on the mouse... i guess it switches off the mouse entirely together with the RGB when using the "switch off" in the app... changing this setting to "do nothing" some how fixed my mouse not waking up issue... will keep it this way for the time being...
