Please help. Is there a update or how do I reinstall?
Thanks,
JohnI submitted the above question, later finding that it has been answered by Buller already. No one need reply as Buller's answer seems to solve the problem for others, and I'll try that.

"/System/Library/Extensions/PACESupport.kext"
After finally installing Snow Leopard today and updating to 10.6.4, I've been getting this error message appear sporadically:
System extension cannot be used.
The system extension "/System/Library/Extensions/PACESupport.kext" was installed improperly and cannot be used. Please try re-installing it, or contact the product's vendor for an update.
How can I fix this?
Thanks.The extension is not an Apple-supplied one. It is an obsolete anti-piracy extension, suppled by Pace Anti-Piracy, Inc. & installed with a few applications such as older versions of Cubase. See Apple > Support > Discussions > Mac OS X v10.4 Tiger > Installation & Setup > PACESupport removal for more info about it & how to get rid of it.

//System/Library/Extensions/AppleUSBEthernetHost.kext
I got a message saying that this: //System/Library/Extensions/AppleUSBEthernetHost.kext was not installed properly and needed to be reinstalled. How do I do that?
Thanks to you both, this fix worked for me too, after long ignoring the error message and vainly waiting for Apple to get around to an update.
Then last night I lost my Internet cable connection, which uses Ethernet between the modem and my iMac (Max OS X 10.6.8). At first, I blamed my ISP because the modem played up for a while, but after I rebooted it a few times, it returned to normal, but I still couldn't get online. I suspected, rightly or wrongly, that this faulty kernel extension might be the culprit. It took me 90 minutes' fiddling to obtain a slow Internet link, but that enabled me to download iTunes 11.4 from Apple.
I cautiously created a "Pre-trash" folder in which I dumped the non-functioning AppleUSBEthernetHost.kext and a back-up of iTunes library files before using the iTunes installer, with an eye on the open //System/Library/Extensions finder window. When the new kernel extension popped up in it towards the end of the installation, I noticed that it bore the date July 29, 2014! Its predecessor dated from mid-2009. This is not the first time in many years that an iTunes upgrade via Software Update has caused problems, usually corrected by downloading directly from the Apple site.
I fixed permissions for good measure and have found that my Internet connection is also nice and fast again, but I have no idea whether that's pure coincidence. -

How do I fix or reinstall?Open the AppleScript Editor in the /Applications/Utilities/ folder, copy and paste the entire following line into it, and press the Run button:
do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges
If it doesn’t work, throw that item away and then reinstall iTunes.

"/System/Library/Extensions/CDSDAudioCaptureSupport.kext"
Hello, I have this; "/System/Library/Extensions/CDSDAudioCaptureSupport.kext" How can I fix it from Terminal?
Thank you!Do you see the file in the location indicated?
Do you have a backup of your hard drive and can you find the component on it?
Sometimes running a Snow Leopard updater may install the component if it has been updated since the original version of Snow Leopard. In the end you may need to reinstall your operating system using your Snow Leopard installer disc. Alternatively you can extract individual components from an installer disc using the Pacifist utility.
Kappy: How to Use Pacifist to Replace Deleted or Missing OS X Components - http://discussions.apple.com/message/9044169 and another https://discussions.apple.com/message/17864069
Before doing any of this I would boot from your installer disc and run Disk Utility to repair your hard drive. Components should not just go missing and this may indicate more serious issues with your files. -

I have just updated my Dymo Label Program. It installed just fine, then the above statement appears stating that this extension was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. I don't know what it is from nor who the vendor might be. The label program installed fine, but it will not print, and I keep getting a statement that my printer is off line. I get it back on line and it goes off line each time I try to print. Any help would be appreciated. Thank you.
It's a component of an obsolete third-party system modification called "Spin Doctor." Follow the developer's instructions to remove it. If you can't find those instructions, see below.
Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
/System/Library/Extensions/CDSDAudioCaptureSupport.kext
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Empty the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return. -
Hi,
I received an EPSON Printer Software Update (vers 2.18) on 30 Aug 2014 and I have not been able to print docs since.
I received the same Update on 20 Sept 2014 but the result is the same.
Whilst these updates were being downloaded an error message described the fault lying in the /System/Library/Extensions/AppleUSBEthernetHost.kext
Is it possible that EPSON has corrupted my Apple drivers?
George.The error is caused by the iTunes update. Delete the kext file, download and install iTunes from the Apple web site, it will re-install a new kext file.
