How to detect USRP usb type?

Question

When i include uhd/usb_control.hpp in my main.cpp :

#include <uhd/transport/usb_control.hpp>

/* Some other includes */

int main (void)
{
    uhd::transport::usb_control::sptr usbSpeed;

    usbSpeed = uhd::transport::usb_control::make(handle, 0);
    /* `handle` is a `usb_device_handle::vid_pid_pair_t` */
}

I got error from here :

static sptr make(usb_device_handle::sptr handle, const int interface);

Error:
unexpected token struct. Did you forget a ';'
struct: missing tag name

And another strange error in:

usbSpeed = uhd::transport::usb_control::make(handle, 0);

Error:
Cannot convert argument 2 from int to const int

The only implementation that i find for uhd::transport::usb_control::make is uhd/transport/usb_dummy_impl.cpp which only throw an exception.

Environment information:
Compiler : MS Visual Studio 2017
OS : MS Windows 10
C++ Standard : 17

How to fix those errors ? I only what to detect the USRP usb type. For this i read the uhd source code and i find the uhd/transport/usb_control.hpp, But I have encountered those errors.

Answer 1

maybe the cause of this unexpected behavior is related to your included files and a conflict between some of them, as you mentioned in addition of #include <uhd/transport/usb_control.hpp> you have some other includes. i suggest move this include line upper and lower of other includes and test your code again.

wish my suggest be useful.
