You may also reset the USB2 IQ module from the Virtual Media dialog box. This action will reset 
every form of USB media on the target device, and should therefore be used with caution, and only 
when the target device is not responding.
Virtual media session settings
Virtual media session settings include locking, mapped drives access mode and encryption level. 
See Managed Appliance Session Settings on page 171.
Table 19.5 describes the virtual media session settings on the supported KVM switch.

Description
Locking
The locking option specifies whether a virtual media session is locked to the KVM 
session on the target device. When locking is enabled (which is the default) and the 
KVM session is closed, the virtual media session will also be closed. When locking is 
disabled and the KVM session is closed, the virtual media session will remain active.
Mapped drives access 
mode
You may set the access mode for mapped drives to read-only or read-write. When 
the access mode is read-only, the user will not be able to write data to the mapped 
drive on the client workstation. When the access mode is read-write, the user will be 
able to read and write data from/to the mapped drive.
If the mapped drive is read-only by design (for example, certain CD/DVD drives or 
ISO images), the configured read-write access mode will be ignored.
Setting the read-only mode can be helpful when a read-write drive such as a mass 
storage device or a USB removable media is mapped, and you wish to prevent the 
user from writing data to it. 
Encryption level
You may configure up to three encryption levels (or none) for virtual media sessions. 
Any combination is valid. The choices are: DES, 3DES, 128-bit SSL and AES. The 
default is no encryption (no encryption levels selected).
