Troubleshooting
This section is an aid to resolving problems occurring in the
previous sections.
Software Issues
The
USB
device
should
install
without
difficulty
automatically. Make sure that the installation finds and uses
the driver contained on the CD. A reboot of the PC may be
necessary afterwards.
If Windows suggests that the located USB driver is not the
driver of this device, please run the program USB_ID that
will be found in the root directory of the CD.
If the program is started before the USB Interface board is
plugged in, the program will try for some seconds to
communicate with the device, and will then stop with an
error box, after which the program will terminate. Make sure
the USB is connected and then restart the program.
The software can have unpredictable effects when used in
conjunction with a USB hub. It is recommended that a direct
connection is made to the USB Interface board.
Hardware Issues
It is possible under most circumstances to power the board
directly from the USB cable. However some patterns may
draw peak current in excess of 500mA, and under these
circumstances behavior of the USB is very dependent upon
PC hardware. If any problems are encountered, such as
patterns stopping prematurely, it is recommended to
connect to a powered hub.
Occasionally it might be necessary to disconnect the USB
cable and re-insert it into the board.
