libusbp failed to initialize generic interface

I'm working on some code to read/write a microcontroller's output. I'm fairly new to this, but from my understanding, I've installed all the necessary drivers required to read a navX2-micro's information.

I decided to use libusbp.

I can see ASCI when I access the COM PORT on PuTTy, but when I try to run the libusbp::generic_interface with a device from libusbp::list_connected_devices it returns either:

Error: Failed to initialize generic interface.  Device is attached to an incorrect driver: usbser.
Error: Failed to initialize generic interface.  Device is attached to an incorrect driver: usbccgp.
Error: Failed to initialize generic interface. Could not find interface 0.

I've followed the code from libusbp's example.

I've read every online post about libusbp I could find, and I've made no progress. Thanks in advance.

Solution

  • Use libusbp only to retrieve the name of the virtual serial port, perhaps depending on other information it can provide. This is from its project site:

    Can retrieve the vendor ID, product ID, revision, and serial number for each connected USB device.
    [...]
    Can retrieve the names of virtual serial ports provided by a specified USB device (e.g. "COM5").

    Then use that name for standard file functions to connect to the device.
