Please check the "Hardware ID" of the HID device by the device manager. Do you see a device look like followings? And also check if the STATUS LED (LED3) on the board is blinking.
This ID is used to bootload a firmware into the KitProg PSoC 5LP device. There are several possible reasons.
1) The RESET button is pressed when the break-away board is attached to your PC. The KitProg device is going to enter to the bootload mode.
2) The target board or the break-away board has a large capacitor between XRES and VSS. When the break-away board is inserted while the capacitor is discharged, the XRES signal is recognized as LOW when the power supplied to the break-away board.
