What was you doing at the time the problem started? You may have Killed your USBJTAG NT. Have you tired to detect a different target?

Typically this is a burnt out signal. You could damaged one or two of the chip in the USB JTAG NT.
What happened when you do this?
Since you are "finding" JTAG pins on ST40 target, it is likely you have misplaced the pins that kills several pins.

No, there is nothing to program CY7C6813A. If this chip is damaged, replace is should work. If you damaged the CPLD then you need to reprogram it.
