USB virtual desktop (model U170) user guide
Minimum system requirements
Host computer
For multiuser applications the host computer operating system can be Windows Server 2003 R2 SP2 (Standard or Enterprise Edition,
Almost any modern PC may be used to host NComputing vSpace software. The guidelines below are a good rule of thumb for determining how many users you can expect to have a native experience running general productivity software applications.
Note: The U170 requires USB 2.0 controller(s) for operation. In addition, some older PCs may have difficulty booting with U170 devices (or other
The table below describes the maximum bandwidth of the USB bus for modern PC motherboards. Some PCs may contain multiple EHCI controllers that can double or triple the available bandwidth. These systems will have better video performance when running more than 4 U170 devices on a PC. To take advantage of multiple controllers, connect any downstream hubs back to the PC directly rather than connecting all U170s downstream of one USB connection. Adding an additional USB controller card to a PC is also an option for large deployments.
