Table 8-34. View PCoIP General Session Variables
(Continued)
Setting Description
Configure PCoIP USB allowed and
unallowed device rules
Specifies the USB devices that are authorized and not authorized for PCoIP
sessions that use a zero client that runs Teradici firmware. USB devices
that are used in PCoIP sessions must appear in the USB authorization
table.
USB devices that appear in the USB unauthorization table cannot be
used in PCoIP sessions.
You can define a maximum of 10 USB authorization rules and a maximum
of 10 USB unauthorization rules. Separate multiple rules with the vertical
bar (|) character.
Each rule can be a combination of a Vendor ID (VID) and a Product ID
(PID), or a rule can describe a class of USB devices. A class rule can allow
or disallow an entire device class, a single subclass, or a protocol within a
subclass.
The format of a combination VID/PID rule is 1xxxxyyyy, where xxxx is
the VID in hexadecimal format and yyyy is the PID in hexadecimal format.
For example, the rule to authorize or block a device with VID 0x1a2b and
PID 0x3c4d is 11a2b3c4d.
For class rules, use one of the following formats:
Allow all USB
devices
Format: 23XXXXXX
Example: 23XXXXXX
Allow USB
devices with a
specific
class ID
Format: 22
class XXXX
Example: 22aaXXXX
Allow a specific
subclass
Format: 21
class-subclass XX
Example: 21aabbXX
Allow a specific
protocol
Format: 20
class-subclass-protocol
Example: 20aabbcc
For example, the USB authorization string to allow USB HID (mouse and
keyboard) devices (class ID 0x03) and webcams (class ID 0x0e) is
2203XXXX|220eXXXX. The USB unauthorization string to disallow USB
Mass Storage devices (class ID 0x08) is 2208XXXX.
An empty USB authorization string means that no USB devices are
authorized. An empty USB unauthorization string means that no USB
devices are banned.
This setting applies to View Agent only and only when the View Agent
desktop is in a session with a zero client that runs Teradici firmware.
Device use is negotiated between the endpoints.
By default, all devices are allowed and none are disallowed.
