I have USB problem with my application with this uc. Your User manual UM0551 "USBHID demonstrator" would be useful and thanks to the ST support, I have received this project and soft to install in my PC.
but I don't have the source code embeddedmicrocontroller.
I suppose after my work that we configure the speed, the mode, the number of bytes within the Embedded code and not side to HID code in PC.
thanks for your help, best regards.
