vendorId and ProductId

Arun Cyriac

Hi all,

How can i get vendorId and Productid of the usb connected. Which Api can be used from a middleware application?

From the link www.keil.com/.../_u_s_b__device__descriptor.html , i understood DEVICE DESCRIPTOR can be used.

But how this can be called in a function??

Regards
Arun

    Hi ,

    I am using Keil-rtx and CMSIS driver for usb.

    For STM32Cube driver ,i found following code which give Vendor Id and Product id of usb.
    Refernce Link:
    github.com/.../usbh_msc.c

    ///code for STM32 cube
case MSC_READ_INQUIRY:
        scsi_status = USBH_MSC_SCSI_Inquiry(phost, MSC_Handle->current_lun, &MSC_Handle->unit[MSC_Handle->current_lun].inquiry);

        if( scsi_status == USBH_OK)
        {
          USBH_UsrLog ("Inquiry Vendor  : %s", MSC_Handle->unit[MSC_Handle->current_lun].inquiry.vendor_id);

          USBH_UsrLog ("Inquiry Product : %s", MSC_Handle->unit[MSC_Handle->current_lun].inquiry.product_id);

          USBH_UsrLog ("Inquiry Version : %s", MSC_Handle->unit[MSC_Handle->current_lun].inquiry.revision_id);

          MSC_Handle->unit[MSC_Handle->current_lun].state = MSC_TEST_UNIT_READY;
        }
        if( scsi_status == USBH_FAIL)
        {
          MSC_Handle->unit[MSC_Handle->current_lun].state = MSC_REQUEST_SENSE;
        }
        else if(scsi_status == USBH_UNRECOVERED_ERROR)
        {
          MSC_Handle->unit[MSC_Handle->current_lun].state = MSC_IDLE;
          MSC_Handle->unit[MSC_Handle->current_lun].error = MSC_ERROR;
        }
        break;


    ///////////////////////////////////////////////////////////////////////////////

    but, since i am using CMSIS driver these functions are not provided.
    Is there any method to find usb details with CMSIS driver.

    Regards
    Arun
