Symmel Posted December 27, 2022 Share Posted December 27, 2022 Merry Xmas and Happy New Year My machine is running perfectly with 12.6 but when upgrading to 13.1 no USB ports are working. Have tried usb mapping but no luck. Any suggestions?

FirstTimeCustomac Posted December 27, 2022 Share Posted December 27, 2022 @Symmel UHCI USB stack is removed in Ventura. Read here. To use keyboard/mouse, you have few options to choose from. - PS2 Keyboard/Mouse if you have one around. - USB 2.0 hub to force EHCI - USB 3.0 PCIE expansion card. 1 Link to comment Share on other sites More sharing options...
Symmel Posted December 27, 2022 Author Share Posted December 27, 2022 Thanks for the reply. I have tried with a PCIE USB 3.0 expansion card with no luck. I'll by a USB 2.0 hub tomorrow and see how it goes. Happy New Year Link to comment Share on other sites More sharing options...
