installing via unibeast, get "still waiting for root device"

[RehabMan]

I have the same problem for the installation, "Still waiting for root device" with the USB key plugged into a USB3 port. But the problem is that on my laptop , I only have USB3 ports.
Is there a solution to install with a USB3 port?

This post is for Yosemite, but most of it applies to any version, especially if you're using the new Unibeast.

Thank you for your answer.
I have tried using " USBBusFix=Yes USBLegacyOff=Yes " and " USBLegacyOff=YEs USBBusFix=Yes EHCIhard=Yes EHCIacquire=Yes " and I still have the same message "Still waiting for root device".
I also look if there were options in the BIOS but there is not .
For information, I try to install Yosemite using Unibeast 5.0.2.

Read carefully. Your problem is you don't have GenericUSBXHCI.kext in /Extra/Extensions.

You could also try different USB ports. You might find a USB2 port that works...

I only have USB3 ports ...

As far as I know the ProBook 4530s has both USB2 and USB3 ports (and in some cases, only USB2).

Look at the forum you're posting in...

what if you only have usb 3.0 on your laptop

The ProBook has both, so not a concern for you.

In the case of loading the installer, it is more likely a USB issue (I think you are thinking of the SATA/AHCI issue that is only an issue with ML).
Usually, people run into this with booting the installer because they are trying to use a USB3 port instead of USB2.

Bottom line... try another USB port on your laptop...

HOLY CRAP!!! This worked for ME!! Well not quite, both my ports were USB 3.0 but i had to go into the BIOS settings to disable the USB 3.0 option and it downgraded both to 2.0.
