CDC Error : This device cannot start. (Code 10)
« on: March 06, 2014, 05:57:25 pm »
Hello folks !

Here I am with one more issue.

I am trying to build a USB CDC Device to communicate over the virtual COM port using MAX3421.

I have an INF file which installs for the device and the device is assigned a COM port too !
However, along with the COM port I get an exclamation mark and the message: This device cannot start. (Code 10).

I had googled it and found that there are many reasons for this error.
As of now, I am not able to figure out the issue.

Below are my device and config descriptors.


const unsigned char DD[]= // DEVICE Descriptor
{
  0x12,            // bLength = 18d
  0x01,            // bDescriptorType = Device (1)
  0x00,0x02,     // bcdUSB(L/H) USB spec rev (BCD)
  0x02,            // bDeviceClass,
  0x00,            // bDeviceSubClass,
  0x00,            // bDeviceProtocol
  0x40,            // bMaxPacketSize0 EP0 is 64 bytes

     
  0x3B, 0x0C,    // idVendor(L/H)
   
  0x34, 0x12,    // idProduct(L/H)

  0x02,0x00,     // bcdDevice
  0x01,            // iManufacturer
  0x02,            // iProduct,
  0x00,            // iSerialNumber
  0x01             // bNumConfigurations
};

const unsigned char CD[]= // CONFIGURATION Descriptor
{
    //Configuration Descriptor

    0x09,         // bLength
    0x02,         // bDescriptorType = Config
    0x3A,0x00,  // wTotalLength(L/H) = 58 bytes

};


There is no other data sent or received at this point.

Any help is greatly appreciated ! Thanks for your time !

Found the issue !!


0x02,         // bNumInterfaces


whereas, I have only one interface.
