Version 4.13.0

STM32Cube V1.0 <-- don't know what this is about.

In the datasheet for STM32F042x4, STM32F042x6 (ST DocID025832 Rev 4), USB 2.0 full-speed is included.  I have not yet found any provisos for USB 2.0 FS not being available for STM32F042P6.  I've already bought the chips, but CubeMx persistently grays out the USB.  What do I have to do to get USB on STM32F042P6?

Hi, 

I confirm USB is not available by default for STM32F042FxPx.

It will be available when checked ''Pins PA11/12 instead of pins PA9/10'' checkbox for SYS.

You should remap the USB pins. Check the SYS -> Pins PA11/12 instead of pins PA9/10 checkbox.
