Adding an Extension Cable or Hub to a Previously Recognized USB-to-Serial-Port Adapter causes serial device to be reconfigured.

Issue:

Adding an Extension Cable or Hub to a Previously Recognized USB-to-Serial-Port Adapter causes serial device to be reconfigured.

Product Line:

NetBotz

Environment:

NetBotz and RS232 sensor connections using USB

Cause:

If you add an extension cable or hub between the appliance and a USB-to-Serial-Port adapter or hub after the USB-to-Serial-Port adapter or hub has been connected to your appliance, all of the serial ports on the converter are recognized as new ports by the appliance.

Resolution:

If you previously configured serial devices on these ports, use the Serial Devices task to reconfigure these devices.
