Hi, today I found an pretty unusual bug while doing some projects with the USB CDC, my code, out of the blue, showed hundreds of errors, after some diggins, me and a friend, found out that in the usbd_def.h, the TypeDef of "USBD_StatusTypeDef" was changed with an "q", I think it must have been some mistake while updating the libraries.

Anyway, just change the letter "q" in the line 209 to "USBD_StatusTypeDef" of the usbd_def.h folder and the errors should disappear.

Hello @Cde M.1 ,

Thank you for this clarification.

I made some tests using STM32CubeIDE.1.12.0 version and the STM32Cube_FW_F1_V1.8.0 firmware version and I didn't find any issue.

The "USBD_StatusTypeDef" is well described in line 209.

So, I advise you to download and to use the last firmware version of STM32CubeF1.

Please let me know if the problem is solved.

Hello @Cde M.1 and welcome to the community :smiling_face_with_smiling_eyes:,

Could you please provide more details on the issue:

Which STM32 product you are using?
Which STM32CubeMX and STM32CubeIDE versions are you using?
Which Cube firmware version are you using?

Thank you.

Hi @KDJEM.1 , I am using the STM32F103C8Tx - LQFP48. (BluePill).

The STM32CubeIDE version is the 1.12.0 (But it was appearing in the 1.9, but I updated it and even reinstalled while trying to fix the error).

The firmware I am not 100% sure in wich version it was, but since I updated the CubeIDE and even reinstalled it (with the latest versions), I think it might be the latest.

If you need any more information, feel to free to ask, I will be glad to help.

Thank You.
