The device individual identification function cannot be used for devices from which the USB device information cannot be obtained because the information is necessary for individual identification.
Before using the USB device individual identification function, perform an execution test using a USB device that has been used before.
When using the USB device individual identification function, the built-in floppy disk drive connected by USB must be registered as well. In addition, the floppy disk drive that is not connected by USB cannot be identified and thus cannot be registered.
If reading prohibition and export prohibition functions are not configured in the File export/read, the USB device individual identification function for Windows Explorer will not be run.
Specifically, even if Read only, Read and Write by file Export Utility only or Write by file Export Utility only has been set in Access settings of the USB device registered in List of available USB devices in the File export prohibition > Individual Identification Feature > Detailed setting window, reading and exporting through Windows Explorer cannot be prohibited. The file Export Utility will run according to the settings.
When the individual identification function is used for a USB device with the lock function, register by using the information of the USB device in the unlocked state.
Selected multiple USB devices with same Device name and Internal serial number but different Identification methods in the File export prohibition > Individual Identification Feature > Detailed setting -Select USB device window of the Management Console. The USB device identification function may run abnormally.
If the USB device individual identification function does not work according to the policy set to USB devices, it is possible that the device failed to be recognized by the operating system.
In this case, reconnect the USB device. Restarting the operating system may not be sufficient to make the function work according to the policy.
If Allow to use all USB devices registered in Management Server is set to Yes and the USB registered to the Management Server on the client (CT) is inserted and then soon removed, a device configuration change log (violation) is collected.
This is to avoid creating a device change log as a normal log when another USB device is inserted while the Management Server is being referenced.
If the USB device individual identification function is used, a device may not automatically start when it is inserted.
Only USB-connected CD/DVD drives can be targeted for individual identification.
Even if it looks like a built-in CD drive, if it is USB connected internally, it is recognized as USB connected.
The target CD/DVD drives are those recognized as CD/DVD by the operating system.
Both virtual CD drives and USB flash memory recognized as CD/DVD are treated as CD/DVD drives.
One USB device may be recognized as multiple drives (for example, as a removal disk and a CD/DVD drive) on the operating system depending on the device.
To allow and register this kind of devices, register the USB device information for each drive. If manufacturer ID, product ID, or serial number is different, all information of the drive to be allowed must be registered. If manufacturer ID, product ID, and serial number are the same, only one drive needs to be registered.
