[SOLVED] no USB mouse after 10.10.3 update

Recommended Posts

Hi,

I updated yosemite without any problems to 10.10.3, though my USB mouse isn't working anymore. I've tried all USB ports, USBBusFix=yes, turning USB Legacy on/of, even a different mouse but no luck. Verbose mode shows that iousbfamily is having difficulties emurating the device. I had that message in 10.10.1 too but after plugging the mouse out/in it worked but that doesnt work in 10.10.3 either. My usb keyboard works fine though. Any suggestions?

I forgot to mention that I also rolled back the USBfamily and HID kexts to the onces from 10.10.1, but that doesn't work either.

Hi Rico, I have this same issue. Just that none of my USB ports are working.

 

Guess I have to get a PCI keyboard and mouse first.
