We just start using EERM, the environment is quite the latest: EEFF 4.1.0 on ePO 4.6.4. We have issue ejecting the USB drives although all application/windows have been closed. A generic pop-up windows will appear, either saying "This device is currently in use. Close any programs or windows that might be using the device, and then try again." or "Windows can't stop your 'Generic volume' device because a program is still using it. Close any programs that might be using the device, and then try again later."
Multiple attempts will not release the USB drive.
Upon checking by using an application called "Unlocker", we found out that the MfeFfCore.exe process locks the USB drive. Please refer to the attachment.
When we select "unlock all", the USB disk can be successfully ejected. Any suggestion to resolve it?
I can confirm that we also have this problem.
We are testing EEF 4.1 with MA 4.6.2. With EEFF 4.1 you cannot eject a USB device with the messages you have stated. This did not happen with EEFF 4.0 so suspect it is bug in 4.1.
Further testing shows you can eject if done via My Computer and eject from there, but that is not acceptable and only a workaround.
Until fixed we shall not be rolling 4.1 out.
Do McAfee actually test their patch releases? ;-)
Were are also testing EEFF 4.1.0. at the moment and I also already noticed the locked USB devices.
After EEFF is installed it's not possible to safely eject an usb drive anymore.
Hopefully this will be fixed asap...on 2/18/13 7:26:31 AM CST
I can also confirm this with eeff 4.1, we have an incident open for it.
Additionnal data: We are using Windows XP in our environnement. The XP with limited privileges are having the messages, but if administrator rights are given, the behavior is not the same and USB can be ejected. Anybody with similar experience?
McAfee have officially recognised the problem - KBase article - https://kc.mcafee.com/corporate/index?page=content&id=KB77515&actp=LIST_RECENT
If you require the eject function to safely remove USB devices (which is probably most people) I would recommend you don't upgrade to EEFF 4.1 until McAfee issue a fix.
I have had a POC package from McAfee (EEFF 220.127.116.118) to test and it resolved the problem i.e. USB device now safely ejects. I will now wait for a RTW update, before deploying to my live enviroment.
