No Mouse and Keyboard after Install Completes (working in Safeboot though)

Recommended Posts



I have installed Yosemite-Zone 10.10.1 on my HP Z400 desktop, everything seemed to be working fine during install, but once the initial boot after install the mouse and keyboard (both USB) are not working.  I have tried the following:


- USBBusFix=Yes (No Result)

- Changing USB Ports (No Result)

- Safeboot (WORKING)


Have can it work smoothly in safeboot but not in normal boot, and what am i missing or haven't i tried?


Thanks for you assistance.

Hopefully someone with a Z400 or someone with some insight can respond to this.  I have an HP z400 with the same specs that has been absolute nightmare installing Mavericks.
