DLPLCR4500EVM: Cannot find manufacturer ID while uploading new firmware, in Windows 10 v18362

Hi Lam,

Welcome to TI E2E forums! I'm sorry you had to face this issue. This is a known issue in the LCR4500 GUI on Windows 10 platforms. We'll be releasing a new version of the GUI soon, in which this issue will be fixed. Kindly stay tuned! If it is urgent, and you can compile the GUI QT project, we can provide you a code fix that you can implement and recompile the GUI to fix the issue.

Thanks & Regards, Hirak.

Hi Lam, 

Please find the required code changes below:

1. file: dlpc350_usb.cpp
Replace the definition of function ” DLPC350_USB_Open()” with the code given below:

int DLPC350_USB_Open()
{
    // Open the device using the VID, PID,
    struct hid_device_info *hid_info;
    hid_info = hid_enumerate(MY_VID, MY_PID);
    if(hid_info == NULL)
    {
        USBConnected = 0;
        return -1;
    }

    DeviceHandle = NULL;

    if(0 == hid_info->interface_number)
    {
        DeviceHandle = hid_open_path(hid_info->path);
    }
    else
    {
        struct hid_device_info *hid_next_info = hid_info->next;

        if(hid_next_info != NULL)
        {
            DeviceHandle = hid_open_path(hid_next_info->path);
        }
    }

    if(DeviceHandle == NULL)
    {
        USBConnected = 0;
        return -1;
    }

    USBConnected = 1;

    return 0;
} 

2. file: mainwindow.cpp
