Hi MCU Lüfter,

You find it

http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00158241.pdf

A useful doc for HID.

http://www.st.com/stonline/books/pdf/docs/14711.pdf

But I have a problem:

when I connect my primer 1 to the computer I get:

USB device not recognized

Currently, this hardware device is not connected to the computer. (Code 45)

I heared that there is a ''.inf'' file to install. Is that right?

Thanks for you participation.

Thanks,

Po

Hi MCU,

Which STM32 device are you using?

I have posted a code here that will make STM32F107's USB to act as a Virtual COM port. You just need to setup the GPIO pins corresponding to your USB properly.. It should work right away:
