In the device manager application, please select the menuitem View>Devices by connection and find the KitProg device in the device tree.

What can you see at the USB Composite Device?

LED1/3/4 always ON is more likely to indicate the current running application inside PSOC 5 LP is the custom FW.

Try to press SW4 to switch to KitProg.

Hi  WangS:

It looks your PSoC5 inside KitProg FW is broken. The KitProg FW can be restored under bootloader mode but not bootloaded.

Please try the steps described in the following doc chapter 10.2.1.1 Restore PSoC 5LP Factory Program Using PSoC Programmer
