Hello,

 I am trying to simplify and linearize USB hot functionality for specific task. USB Host example (http://www.st.com/internet/com/SOFTWARE_RESOURCES/SW_COMPONENT/FIRMWARE/stm32f105_usb_host_lib.zip -USBH_HID_KBrd_Mouse) in IAR works perfectly with STM32F107 MCU. I traced some commands and put them step by step. Somehow I receive no data from USB device.

Mine C code looks like this:

  uint8_t speed = HCD_GetCurrentSpeed(&USB_OTG_FS_dev); // dummy read

  USB_OTG_BSP_uDelay(5000);

  USBH_Open_Channel(&USB_OTG_FS_dev, 1, 0, 2, 0, 0x40);

  USB_OTG_BSP_uDelay(5000);

  USBH_Open_Channel(&USB_OTG_FS_dev, 0, 0, 2, 0, 0x40);         

  USB_OTG_BSP_uDelay(5000);

  USBH_Get_DevDesc(&USB_OTG_FS_dev, &dev_desc, 8) ;

  USB_OTG_BSP_uDelay(5000);

  USBH_CtlSendSetup(&USB_OTG_FS_dev, buff2, 0);

  USB_OTG_BSP_uDelay(5000);

  USBH_CtlReceiveData(&USB_OTG_FS_dev, buff, 8, 1);

  USB_OTG_BSP_uDelay(5000);

  HCD_GetCurrentFrame(&USB_OTG_FS_dev);

  USB_OTG_BSP_uDelay(5000);

  HCD_GetCurrentFrame(&USB_OTG_FS_dev);

  USB_OTG_BSP_uDelay(5000);

  HCD_GetCurrentFrame(&USB_OTG_FS_dev);

  USB_OTG_BSP_uDelay(5000);

  USBH_CtlSendData(&USB_OTG_FS_dev, buff, 0, 0);

  USB_OTG_BSP_uDelay(5000);

  USBH_Get_DevDesc(&USB_OTG_FS_dev, &dev_desc, 8);

I have inserted some debug information in (1)usbh_hcs.c (2)usbh_stdreq.c (3)usbh_ioreq.c (4)usb_regs.c (5)usb_core.c files. Here is debug output port from my code:

-1- USBH_Alloc_Channel (00)

-1- HC_GetFreeChannel

-1- USBH_Alloc_Channel (80)

-1- HC_GetFreeChannel

-4- USB_OTG_USBH_handle_port_ISR

And there is debug from original example:

-2- .USBH_ParseDevDesc

Hardware USB logger shows that there is no difference in USB communication. See screenshots:

So why I receive no data in my application? What else should I debug?
