Sun Ray Software works with various mass storage USB devices such as flash disks, memory card readers, zip drives, and disk drives on Sun Ray Clients. Data CDs and DVDs can be read but not written. Other end-user peripherals such as USB headsets, printers, and serial devices can also be used.
There are multiple ways to access peripherals connected to a Sun Ray Client, based on the type of Sun Ray session you are using:
Oracle Linux or Oracle Solaris Sessions - You can access the device through the device links and nodes automatically created on the Sun Ray server. See Section 15.4, “Accessing Serial Devices and USB Printers” for details. USB mass storage devices are automatically mounted, which is described in Section 15.5, “Accessing USB Mass Storage Devices”.
USB-to-serial adapters are not accessible through the generated device nodes. You must use USB redirection in a Windows session to access a serial device connected through a USB-to-serial adapter.
Windows Sessions Using USB Redirection - USB redirection is the recommended way to access USB devices connected to Sun Ray Clients when using Windows sessions. USB device redirection requires that the USB device redirection component is installed on the Windows system. See Section 17.6, “USB Device Redirection” for details. Although most of the information in this chapter is not applicable when using USB redirection, device services still need to be enabled.
Windows Sessions Using Logical Device Mapping - Without USB
redirection, you can use the -r
option of the uttsc
command to create a logical device mapping to the device being managed on the Sun Ray
server, as described in this chapter. For example, the -r
disk:
enables
you to create a logical device mapping to a USB mass storage device, where
drive
=path
path
is the mounted disk located at
/tmp/SUNWut/mnt/
on the Sun Ray
server. Other devices, such as serial devices, can also be configured. For details about
accessing serial devices when using the Windows connecter, see Section 17.17, “Accessing Serial Devices”.user
Using logical device mapping with USB mass storage devices provides much lower performance on Oracle Linux than Oracle Solaris due to the design of the Linux mass storage subsystem. For Windows sessions, use USB redirection for optimum performance with mass storage devices.
For the latest list of peripherals tested to work with Sun Ray Software, see the Sun Ray Client and Oracle Virtual Desktop Client Peripherals document.
Once the latest firmware is installed on a Sun Ray Client, no special installation is required for USB headsets to work. Just connect the USB headset to the Sun Ray Client. See Section 15.6, “USB Headsets” for details.
