Windows does not recognize a removable encrypted USB HDD when reconnecting it on a system running Host IPS 8.0

• The USB drive is not clearing its drive reference completely when unmounting the DVD/CD-ROM device.
• The Windows operating system is not recognizing the USB unmount correctly.

Analysis determined there are three variants of encrypted USB drive issues. Each could be experienced concurrently or independently on Windows operating systems. These issues are timing and image specific and could occur with or without Host IPS installed:

• Encrypted USB device password executable hang related to an issue in Microsoft's FASTFAT driver. In some instances, the USB drive authentication executable could hang, preventing initialization of the USB device. McAfee has determined that Host IPS is not at fault. Intel Secrity has implemented a workaround code enhancement (911048) to avoid the issue on systems where this issue could occur. This workaround is included in Host IPS 8.0 Patch 4.
• Encrypted USB device fails initialization the first time it is installed in a system without CD-ROM hardware installed. McAfee has determined that Host IPS is not at fault. This particular failure could occur intermittently on any system regardless of whether Host IPS was installed. McAfee has determined that Host IPS is not at fault and no further action is required by McAfee. 
• Encrypted USB device fails to dismount properly if the user disconnected the drive on a on a system without CD-ROM hardware installed. McAfee has determined in some instances, the USB device failed to load the CD-ROM File System (CDFS) driver during dismount. This fault could occur when the device is removed, but the fault would not become evident unless the device was subsequently attached again at which point the CDFS would not load. McAfee has determined that Host IPS is not at fault and no further action is required by McAfee.
