LPC55S69-EVK USB0 ISP mode not working

Hi,

 

I'm experimenting with the LPC55S69-EVK and was now testing the ISP functionality. I've now noticed that the USB ISP mode only works when using USB1 and not on USB0.

 

Pressing button ISP while plugin in P10 (USB0) doesn't have any response on my PC.

Pressing button ISP while plugin in P9 (USB1 both FS and HS) does work, the drivers are loaded and the device is available.

 

As I can see in the UserManual in chapter 6 paragraph 3 both USB0 and USB1 or supported in the USB HID ISP.

 

Can someone verify this behaviour?

Is this a bug or am I doing something wrong?

 

Thanks!

Tom
