USB Start-up Problem (aka the Audio problem)

[toleda]

the symptom for the USB problem is exactly the same

1 in 10 boots is not the same as every boot; not related. Post to Installation forum.

It's also a workaround, but I didnt change anything but adding an USB2 Hub to one of my Mainboard USB3 connectors, connect keyboard+mouse there and the " Wait_a_minute_till_u_can_type" problem dissapeared.

chrizzle's observation is interesting - i wonder what's going on ?

i noticed that if you switch on screen sharing, you can remotely control the mouse straight away.
on some occasions, the mouse on the real screen turned into a frozen beachball - but was still working via screen sharing.

i wonder if its something to do with the window server ?

has anyone tried the HDMI Audio patch via plist injection ?
if so, does it make any difference?

reading around, it looks like the same probs appear with mavericks etc. so i'm considering ditching this card

Not possible, AppleHDA.kext does not support HDMI audio on a GT 210.

ah thanks for getting back to me, i don't use the HDMI audio (don't use the built-in audio either) just just don't like unsolved problems
i tried the ssdt-1 patch but the machine stuck in the spinning booting screen. verbose seemed to stop after the cpu definitions ssdt so maybe there's a clash on my particular set up.

in the end, i've just removed the HD Enabler1.kext and the machine's doing what i need.

thanks for your explanations

Hey guys, I figured out the cause and the fix.
Put your mouse and keyboard in a usb 2.0 port.
the cause (for me) was a graphic driver interfering with the usb ports.
