Before devices can be accessed on a Sun Ray Client, Sun Ray device services for the device must be enabled. Sun Ray device services can be enabled and disabled with the utdevadm command line tool or from the Security tab on the Admin GUI Advanced tab. Sun Ray device services include USB devices connected through USB ports, internal serial ports, and internal smart card readers on the Sun Ray Client.
Here are the available device services for external peripheral devices:
Internal serial port - Enables users to access the embedded serial ports on their Sun Ray Clients.
USB port - Enables users to access any devices connected to USB ports. This situation does not affect HID devices such as the keyboard, mouse, or barcode reader.
After you install Sun Ray Software, all device services are enabled by default. You can use the utdevadm command to enable or disable device services only in the configured mode, that is, after the Sun Ray Data store is activated.
This configuration affects all the servers in a group and all the clients connected to that group.
The utdevadm command displays the enabled or disabled state of device services.
