USB devices attached to the QuVIS Acuity are automatically detected by the server and mounted as a storage
volume. As a mounted volume, USB drives can be accessed (read-only) from the front panel GUI (PLAY Browser
menu page), QShell command line interface, and other file browser utilities such as FTP and Telnet.
QuVIS servers, including the QuVIS Acuity, automatically assign volume names to mounted USB devices. The
volume naming convention for mounted USB drives is as follows:
1
st
USB drive mounted = USB0:
2
nd
USB drive mounted = USB1 :
Additional USB drives mounted = USB(n+1):
Disclaimer: Please note, due to improper or non-standard implementation of the USB standard into USB storage
devices by the device manufacture, not all USB devices may be supported by the QuVIS Acuity (with CPU 7).
Other factors resulting in a USB device not functioning properly may include:
•
Improper power source - device may require an external power source instead of relying upon bus power.
This was true on prototype versions of the CPU 7. The current production version, however, is able to
provide bus power to a single USB drive under normal conditions.
•
Improper cable length – if the length of the USB cable between the external USB storage device and the
QuVIS Acuity exceeds 2 meters communication may be compromised and the device may not function
properly. In this instance, you must use a shorter USB cable or external USB hub to correct the problem.
•
USB 1.1 devices are not formally supported – Some USB 1.1 devices may work while others will appear to
not function. QuVIS is in the process of investigating formal support of USB 1.1 devices and will, if
possible, provide a software update that will include support for these devices.
