2-16 Remote USB overview

RGS supports remote USB, which allows USB devices connected to the Local Computer (local USB devices) to be

attached to a Remote Computer. Remote USB is supported on Remote Computers running Windows XP, and

enables the Remote Computer to have direct access to the local USB devices as if they are connected directly to

the Remote Computer (see Figure 2-17). For details on remote USB, see Section 6-3, “Remote USB operation

.”

Figure 2-17 Remote Computer can access the local USB devices

In Figure 2-17, two USB devices are connected to the Local Computer. Using RGS, the local USB devices can be

attached to the Remote Computer. The keyboard and mouse always remain connected to the Local Computer, and

cannot be attached to the Remote Computer.

The local USB devices can be collectively attached to a single Remote Computer (see Figure 2-18). The local USB

devices cannot be split between multiple Remote Computers nor can they be collectively attached to multiple

Remote Computers.

Figure 2-18 The local USB devices can be attached to only one Remote Computer at a time.

2-16-1 USB session switching

At RGS 5.1.3, the ability to dynamically move USB devices from one Remote Computer to another was added.

Prior to RGS 5.1.3, it was necessary to first disconnect all RGS connections (sessions) to the Remote Computers,

and then re-establish connections while specifying a new Remote Computer to attach the USB devices to. With

RGS 5.1.3, USB devices can be detached from one Remote Computer, and made accessible by another Remote

Computer without first needing to disconnect the RGS connections. For details on this, see Section 6-3, “Remote

USB operation.”

2-16-2 Isochronous USB support

At RGS 5.2.0, support was added for the USB isochronous data type, which is commonly used for streaming data

devices such as audio and video devices. See Appendix B: USB devices supported by RGS for a list of supported

isochronous USB devices. See also Section 2-17-3, “Support of sound recording devices on Windows

,” for an

overview of the two ways USB microphones can now be used with RGS.
