Hi, i have an discovery STM32F407 board,
using cubemx (4.9.0), opened new project for the STM32F407 discovery board.
enabled USB_OTG_FS "Device Only" mode without SOF and without VBUS.
Selected the CDC class, the clock and every thing is ok, the code generator for IAR.
Compiled and run.

On windows device manager i have new device:
STMicroelectronics Virtual COM Port (COM5)

But i get this error:
This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

configured USB class as custom HID:

This device cannot start. (Code 10)

Extra end collection found or end collection not found.

on another laptop i get "the i\o request was cancelled"

the mouse example works well.
using windows 8.1.
I worked with another manufacture HID example and it works well, so i don't believe it's a driver issue.

Will be thankful for any help, thanks.
