Hello,

I want use USB + SD SDIO. I used standard libraries from ST but I still get following messages:

> MSC Interface started.

USB Device Library v1.1.0 [FS]

> MSC Interface started.

USB Device Library v1.1.0 [FS]

> MSC Interface started.

USB Device Library v1.1.0 [FS]

> MSC Interface started.

Does anyone have an idea how to solve this problem?

With the information provided, not so much.

The STM32F429I-DISCO has some pin conflicts on the SDIO interface, and seem to recall it using the HS interface. But who knows what board you're using.

Ok, well I'm pretty sure none of ST's code targets this board. So you'll need to port any pin and board specific differences. This will require you review the schematics for both boards.

One of the more obvious ones would be that it uses an 8 MHz crystal, and all of ST's EVAL series boards use 25 MHz. So you'll have to address the PLL and HSE_VALUE settings.

The SDIO interface has an arbitrary GPIO used for CARD DETECT

Would recommend you try to confirm the SDIO interface is functional first.
