I need to configure one USB port as an HID host and the second USB port as an MSE host. Is this setup possible?

I will mention at this point that I am connecting to a known working CDC device. I know it is working because I can connect the same port to a PC, and it enumerates properly, and I can pass data to/from the device.In module usbh_core.c function USBH_...

Why isn't the SDMMC code tolerant to interrupts?

But when I remove power (with the 3V battery still connected to Vbat) the date/time values freeze. That is, they remain where they were when to power was removed. How do I make the RTC continue to run during power down? Any help is appreciated.

Hi Pavel,Thanks for the reply :)I am using an STM32H743 MCU for this project. I want to connect the USH HS port to a composite HID device (a Ritek keyboard/mouse). I also need to connect the USB FS port to an MSE device (a thumb drive). I therefore n...

I disagree with you somewhat on this. It seems to me that as long as you use different endpoints you can send a message (packet) to the endpoint without receiving a reply. The reply may come after packets are sent. I think the key to handling composi...

Thanks for the response. The problem I have is I don't understand how to get the example code to talk to both the devices at the same time. The example code will talk to either the mouse or the keyboard but not both. I am already parsing the descript...

It is the second (one multifunction composite device). In fact, it is a wireless Ritek Rii model i4 device with a USB dongle that connects to the HID host. I will check the tiny-USB site but the last time I looked they didn't support the HID host.

Hi AScha.3,Thanks for the reply :)The example you mentioned is for a dual-core STM32H7 device but it may work for my needs. I'll give it a try as time permits.

Can I use both stm32H743 USB ports configured as hosts? By ports I mean the Full Speed port and the High Speed port.

I am having trouble making a USB-CDC host work on a STM32F407 chip. The primary problem is it seems to get stuck in an endless loop in the CDC state ENUMERATION. I originally built the code using the STM32Cube application.

Is there an example USB HID host that supports both a mouse and a keyboard at the same time?

I am using a STM32H743 to access a SD card using the ST micro driver code. I m NOT using interrupts for the MMC however if an interrupt occurs during a file access the code sometimes crashes. By crashes I mean the read routine times out.

I am having trouble getting the RTC to work with battery backup. I am using LSE as the clock and I have enabled the backup domain. I can set the date/time values as expected.
