Anyone managed to get USB running with main clock instead of USB PLL?

I've set main clock to 48 MHz, USBCLKSEL=1, USBCLKUEN toggle, USBCLKDIV=1. Doesn't seem to work.

Btw. none of the examples use USBCLKUEN toggle (and manual says it's needed after USBCLKSEL is set)

Btw2. none of the examples set USBCLKDIV to 1 (manual says 0 is the default, and that means disabled?!)

OK, so I got it working.

Trick is that you have to enable, start and lock USB PLL for USB to work off the main clock. It also works when I set USB PLL to 24 MHz, so it seems it really doesn't use it, just needs it to be enabled.

Anyone from NXP here?
