Installing the USB Driver

Normally, the software installation package will install the USB driver on your computer when you load the ChronoVu software, and no further action will be required.

How can I tell if the driver was properly installed?

To verify that the driver was properly loaded, connect your ChronoVu LA8 to a USB port, bring up the ChronoVu software, and select “About” from the “Help” menu. If the driver is properly loaded, the hardware serial number will be read from the ChronoVu device and displayed on the “About” menu. If the hardware serial number is shown as “Not Available”, the driver may not be properly installed. (Note that you will also get the “Not Available” response whenever the ChronoVu device is not connected to a USB port).

What if the driver is not properly installed?

If you have not rebooted your computer since you loaded the software, try unplugging the ChronoVu device and rebooting your computer. Then connect the ChronoVu device, then open the ChronoVu software. This will insure that the Plug-and-Play (Windows) or udevd (Linux) enumerator has had ample opportunity to install the drivers.

What if the driver is STILL not properly installed?

The installation system has failed to properly install the driver on your system. You will need to install the driver manually.

How do I do that?

On a Windows system, you may need administrative privilege to manually install the driver. To install the driver manually, browse the files in the program installation directory (C:\Program Files\ChronoVu LA8), or on the software CD, to locate the file named “CDM20600.exe”. Double click to run the file. After running this file, the drivers should be installed by the Plug-and-Play enumerator the next time that the ChronoVu device is connected to a USB port. Alternately, you can allow the system to find and load the driver for you. To do this, plug the ChronoVu LA8 into the USB port and wait for the system to ask for the driver location. When asked, specify either the installation directory (where you installed the software) or the installation CD (you’ll have to put it in the drive, of course) as the search location, then allow the system to find and install the driver.

On a Linux system, you must log in as the root user to install the driver. Browse the files on the software CD or in the installation directory tree (/usr/local/share/chronovu_la8) to locate the directory named “LinDriverFiles”. Within this directory, locate the file named “99-usbftdi.rules”. Copy this file to /etc/udev/rules.d as follows:
(cp 99-usbftdi.rules /etc/udev/rules.d)
Unplug the ChronoVu device, and reboot your computer. This should complete the driver installation. If you still have problems, try manually adding one of the following lines to the file /etc/fstab using a text editor:
none /proc/bus/usb usbdevfs defaults,devmode=0666 0 0
or
none /proc/bus/usb usbdevfs defaults,mode=0666 0 0
(for 2.6 kernels use “usbfs” rather than “usbdevfs”)

On a Mac system, you must log in as the root user to install the driver. Browse the files on the software CD or in the application directory tree (/Applications/ChronoVu.app/) to locate the file named “libusb-0.1.4.dylib” that is appropriate to your system (Leopard, Tiger, or Snow Leopard). Copy this file to /usr/local/lib as follows:
(cp libusb-0.1.4.dylib /usr/local/lib/libusb-0.1.4.dylib)
Unplug the ChronoVu device, and reboot your computer. This should complete the driver installation.
