USB speed issue #usb


When I run the zephyr/samples/subsys/usb/mass example for board mimxrt1050_evk everything works fine except is only runs at normal USB Full speed 12M. I have tried to add "CONFIG_USB_DC_HAS_HS_SUPPORT=y" but then it does not work at all. When looking in the code I feel that it has been tried to run it at High Speed but something is missing.  
The corresponding example from NXP McuXpresso environment works as expected with USB High speed 480M.
I have attached the output of my tests for reference.

Can this be fixed, or can you advise me to get it working?
