crystal-less USB on KL27Z

I'm using PE in KDS to configure the USB in HID mode without external crystal.

It is a custom board using the MKL27Z256VLH4, the board is powered by the usb bus.

I use J-Link to debug. On Linux I got enumeration error, on Windows the same.

Here is the components that I'm using:

MCG Lite mode: HIRC

Core clock: 48 MHz

Bus clock: 24 MHz

USB Clock: IRC48M

I didn't touch in any generated files, is it supposed to work just grabbing the components and configuring them to the project?

I have no experience with KDS and PEx, am I missing something?

I installed the KDS 3.0.0 and upgraded it using "Check for updates" inside it, after that I applied the eclipse update from KSDK 1.3.0.

Attached is the project.

If someone has a *simple* example of the thing working for this micro, I'd appreciate.

Thanks!
