Hello
After upgrade from 15.6 to 15.6.1 my wired USB-A Keyboard, Mouse and Printer have stopped working.
The setup is :
MAC Book Pro 16 inch 2019 15.6.1
USB hub has 1xHDMI, 2XUSB-A, 1xUSB-C(power) , 1xEthernet - brand cable matters
What works:
On the same hub - a USB-A memory stick works.
USB-C memory stick connected directly to the Mac works
Bluetooth printer works
Bluetooth mouse works
Display via HDMI works
iPhone 11 connected via USB-C to lightning works.
I have tried using two other USB hubs - does not work
I have also tried another MAC Book Pro 16-inch with 15.6 and this Works.
Just the USB-A Keyboard mouse and printer with does not work with MAC Book Pro 16 inch 2019 15.6.1
I have reinstalled 15.6.1 and it still does not work.
I have tied SMC reset and NVRAM reset and it still does not work
This is a hug problem is support for USB-A input devices is broken.
Please help fix this.
