RTX USB Composite Device HID and MSC

Joseph Moschini

Hardware:
Keil MCBSTM32F400

Software:
Keil MDK V4.53, V4.52, V4.51 V4.50

I have created code to run USB Composite Device HID and MSC-SDIO with out RTX every thing is works fine.

When I try to develop USB Composite Device HID and MSC-SDIO with RTX the MSC always fails to read. The HID side work ok. I changed the code to work with MSC disk image sample no SDIO routine, the MSC and HID work fine. So I am assuming that the sample SDIO driver do not work in RTX USB Composite.

Has anyone had similar issues ???

    For typical USB - SD card reader implementation, SOF interrupt gives regular timing to poll media-detect / write-protect switches. But I'm not sure if this is the case on the RTX-MSC-SDIO library.

    Anyway, as the core source code of the stack is not open, I can't contribute to RTX-USB. It's Keil's business.
