Keywords: USB-II, JTAG, configuration, DLC9, DLC9G, DLC9LP

When I access my Platform Cable USB, the following messages appear in the iMPACT console:

WARNING:iMPACT - Platform Cable USB firmware must be updated. This operation may take up to 10 seconds. Please
do not stop the process or disconnect the cable prior to completion. The cable STATUS LED will be RED for the duration
of the update process.

Solution

Check that the USB port the cable is attached to is a USB 1.1 port. This issue can arise if the cable firmware update is updated on a USB 1.1 port. The work-around is to update the firmware on a USB 2.0 port.
