HP ThinPro 6.1 - Administrator Guide
Windows Explorer, with the name <device label> on <client hostname>; for example,
Bill_USB on HP04ab598100ff.
There are three restrictions to this type of redirection.
●
The device will not appear in the taskbar on the remote host with an icon to eject the device. Because of
this, make sure to give the device a suicient amount of time to sync data after a copy before removing
the device to be sure that the device does not corrupt. Typically, less than one second is required after
the le copy dialog nishes, but up to 10 seconds might be required depending on the device write speed
and network latency.
●
Only le systems supported by the thin client will be mounted. The supported le systems are FAT32,
NTFS, ISO9660 (CD-ROMs), UDF (DVD-ROMs), and ext3.
●
The device will be treated as a directory; common drive tasks like formatting and modication of the
disk label will not be available.
USB redirection of storage devices can be disabled in an individual connection's settings. If desired, you can
disable mass storage redirection altogether. To do this, turn o USB redirection, and then change the registry
keys as described in the following table.
Registry entry Value to set Description
root/USB/root/holdProtocolStatic 1 Makes sure that the USBR type will not be automatically
changed when a connection is set or unset
root/USB/root/protocol local Makes sure that the RDP connection does not attempt to
redirect any devices to the remote session
To completely disable local mounting of USB mass storage devices or to disable the redirection of USB mass
storage devices but still allow other devices to redirect, in the thin client le system, delete the udev
rule /etc/udev/rules.d/010_usbdrive.rules.
RDP printer redirection
By default, RDP has two methods of printer redirection enabled:
●
USB redirection—Any USB printer plugged into the device will show up as a local printer in the remote
session. The standard printer installation process must happen in the remote session if the printer is not
already installed on that remote host. There are no settings to manage locally.
●
High-level redirection—If either USB redirection is unavailable on the remote host or the printer is a
parallel or serial printer, use high-level redirection. Congure the printer to use a local printer spooler,
and the RDP client automatically sets up a remote printer that sends print spooling commands through
a virtual channel from the remote host to the thin client.
This method requires both that the printer be congured on the thin client and a Windows driver be
specied on the thin client because the RDP client needs to specify to the remote host which driver to
use for the remote printer. This Windows driver must match the driver that the printer would use when
locally attached to a Windows operating system. This information is usually found under the Model in
the printer properties.
NOTE: See Serial or parallel printer conguration on page 63 for more information.
