  • Hi

    I want to communicate with the Telit 3G modem that support CDC USB standard.

    1.I search about Winusb and find this page:

    I confused because the description does not match with Visual Studio 2015 .

     

    2.I search in web to resolve this problem I see this page:

     

    3.after correction my project when I compile that I see this error:

    "Error    TRK0002    Failed to execute command: ""C:\Program Files (x86)\Windows Kits\10\bin\x86\inf2cat.exe" /os:10_x64 /driver:C:\Newfolder\USBapp\x64\Debug\USBpac\". The operation identifier is not valid.    USBpac    C:\Newfolder\USBpac\TRACKER    1"

     

    4.I wrote my problem under the page that I mentioned in top but unfortunately Sara do not answer to me.

     

    5.I solved the problem with run inf2cat from Command prompt and make Cat file as you can see:

    "C:\Program Files (x86)\Windows Kits\10\bin\x86>inf2cat /os:10_x86 /driver:c:\newfolder\usbapp\x64\debug\usbpac
    .........................

    6.I find the hardware ID   %DeviceName% =USB_Install,USB\VID_1BC7&PID_0021 and the GUID then put the Inf file .

    and make a Cat file .

  • Is the modem visible in Device Manager with your driver installed?

    What GUID do you use? What is the InterfaceClassGuid parameter when you call SetupDiEnumDeviceInterfaces?

  • first I use the driver from Telit  and find the GUID from Device Manager.But after that some body say we must use Winusb driver for device I uninstall them and allow windows select driver 

    Driver Management concluded the process to install driver usbser.inf_amd64_5cc59e887dec04f4\usbser.inf for Device Instance ID USB\VID_1BC7&PID_0021\357164045031138 with the following status: 0x0

  • So, in Device Manager, is it as a "serial port" with class GUID {4d36e978-e325-11ce-bfc1-08002be10318} or WinUSB device?

  • In Device manager it is a "Serial port" with class GUID {36FC9E60-C465-11CF-8056-444553540000}. This GUID show my Hub GUID I find that you mentioned in my modem INF file. i do not understand WinUSD device? another problem that I said :I have problem to compile my project. and another question :If we have a INF file why we add an INF file to the project? I am confusing!?

    Well, you have a WinUSB driver installed on this device. It will not function as a modem or com port. If you still are confused, please ask in the drivers forum.
