Hi! Please help me with my problem. I have self made board with MK22FN512VLH12. I have problem with USB. If i run USB examples, then my PC don't see my board. All code traced in debug mode without errors. My board based on FRDM-K22F. What could be the problem?
I solve this problem. I don't connect VREG pin to VBUS :smileyhappy: Thanks!
Hi Dmitriy,

Have a great day,

Hi Dmitriy,
What the USB example you are using?
Did you also try the FRDM-K22F board and run the USB code in your PC? Whether this board can work ok on your side?
Have a great day,
