I am using USB MSC driver on a STM32H7 MCU. Is it possible to modify the descriptors in order to avoid Windows autoplay?

Hello @AGhez​ ,

Can you provide more details on what you mean by windows autoplay?

Thanks in advance.

No, autoplay is a windows feature, not a USB feature. The drivers don't dictate this.

[AGhez]

thank you both!

yes, @Walid ZRELLI​ , I mean Windows feature to open the 'Windows explorer' window when connecting a device like an USB disk.

I know that it is possible to disable it for a specific device, so I was thinking that it was something that was requested from the device descriptor!

For definitive answer about the Windows behavior you're welcome to visit the MS forums.

IIRC Windows can disable mass storage function on selected USB devices by h/w ID. Somewhere in the group policy.

Recently Microsoft, in their alternative and inclusive wisdom, has killed the MSDN forums and driven many best experts answering questions out of there.

Hello @AGhez​ 

It is as @TDK said, not a driver feature. It might be possible to disable windows autoplay by placing an autorun.inf file at the driver's root.
