Troubleshooting

This section is an aid to resolving problems occurring in the

previous sections.

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.

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.
