U-MULTILINK and U-MULTILINK-FX

Hi all,

I have a U-MULTILINK Rev D and a U-MULTILINK-FX Rev B. I use them to program the KV58 series microcontrollers from NXP. However, I am experiencing the same issue with both programmers.

The issue is as follows: when I connect the programmer to the computer via USB, the computer does not recognize any COM port, and the blue LED does not light up. When I connect the programmer to the MCU, the other LED on the programmer also does not light up—both LEDs remain off.

I found a forum post mentioning a similar issue, but no solution was provided. Since both of my programmers are exhibiting the exact same issue, I would like to ask for assistance in resolving this problem.

I measured the 3.3V power supply on both programmers, and the voltage level appears to be normal. Please help me troubleshoot this issue.
