OS X 10.6.3 on 10.10: using VM to hardware calibrate monito

[davestelfox@yahoo.co.uk]

Hi I've installed 10.6.3 on a brand new Mac Mini running Yosemite.
I did this because I discovered that my Eizo monitor's calibration software does not work on OS X, but it does with 10.6.
I work with images and need to be able to calibrate about once a month or so.
Wasn't too difficult to get the the VM running.
Now, however, I'm having a having a lot of trouble getting the VM to recognise the monitor's USB connection.
Visually, the monitor is connected via an HDMI cable, so that's not a problem at all.
What I'm talking about is the USB connection from the monitor to the Mac Mini, which allows the calibration to happen - it's a cable that sends information from the calibrator and monitor to the Mac Mini, which the Mac Mini uses to adjust the internal brightness and colour balance of the monitor.
I am new to Virtualbox and not at all technically minded, but I can't find a similar problem here.
Is there a way to assign a USB port to the virtual machine, so it is able to send/receive this information to/from the monitor?
If you could keep answers as simple as possible, and make no assumptions of any knowledege on my part, that would be great – I've been using Virtual Box for less than 24 hours.
Many thanks in advance.

I don't see how what you want to do is possible. Virtualbox guests use the VirtualBox display adapter rather than any built in video cards. The Eizo software would have to be able to manipulate the graphics adapter which I doubt it could.

Perhaps someone else knows something different.

I do not think that the calibration software changes anything in the video card. I think is a software layer that sits on the OS between the OS drivers and the final renderer.

As I said above to Lou, the calibration "algorithm" sits on top of the operating system. So, even if you get this to work (not going to deal with it at the moment), you will apply the calibration on top of the operating system that runs the calibration software, i.e. your VM. As soon as you shut down your VM, the calibration exists no more.

Unless I missed something way obvious and the calibration software really modifies the actual hardware, i.e. the monitor itself. Could you post a link to said software so we can take a look and see what it is supposed to do?

Normally I would agree. I'm just not sure about Eizo monitors. They make a 30" LCD for $20,000 US.
