Hello,I am using the STM32F7 for USB communication as an MSD host and using the usbh_core.c code and all of it's associated pieces. I have it working consistently on USB 2.0 devices (side note: I needed to insert an enumeration retry for certain non-...
Hello,I am having an issue connecting to specific USB mass storage devices with my STM32F769 USB host using the BSP. It seems like the USBH_GetDescriptor function never returns for USB flash sticks with a specific HID PID combination. I am considerin...
Hi All,I have been utilizing the STM32F7 to take and store pictures on USB 2.0 sticks.I have repeatedly run into variation across sticks that requires that I modify the MSC Host HAL supplied by STM. The most recent issue that I have run into is getti...
