USB manufacturer + descriptor with PIC18F4550
PostPosted: Fri Oct 24, 2014 6:15 am     Reply with quote
Dear Everybody,

I'm working with PCWH 5.030 and WIN7 64 bits.

I'm using a virtual COM port with my PIC18F4550 through USB.

My software is working well.

To be perfect, I would like to inform to my board : the manufacturer and the name's board.

I tried this but not working: When I go to the parameters of the board :
I can see for the manufacturer : %ProviderName%
and for the name of the board : Emplacement 0 (Port_#0009.Hub_#0001)

Code:
#define USB_CONFIG_VID 0x0461
#define USB_CONFIG_PID 0x0033
#define USB_CONFIG_BUS_POWER 500
#define USB_STRINGS_OVERWRITTEN

char USB_STRING_DESC_OFFSET[]={0,4,16};

char const USB_STRING_DESC[]={
   //string 0 - language
      4,  //length of string index
      0x03,  //descriptor type (STRING)
      0x09,0x04,  //Microsoft Defined for US-English
   //string 1 - manufacturer
      12,  //length of string index
      0x03,  //descriptor type (STRING)
      'P',0,
      'R',0,
      'A',0,
      'N',0,
      'A',0,
   //string 2 - product
      22,  //length of string index
      0x03,  //descriptor type (STRING)
      'B',0,
      'I',0,
      'A',0,
      'S',0,
      ' ',0,
      'B',0,
      'O',0,
      'A',0,
      'R',0,
      'D',0
};


Does someone have an advice?

Best regards,

Fabrice

Did you read the comment in the descriptor file?:

"// These strings are mostly only displayed during the add hardware wizard.
// Once the operating system drivers have been installed it will usually display
// the name from the drivers .INF."

Thanks Ttelmah for your answer.

You are right, I deinstall the drivers and plug again my board. I saw the name of the board.

It misled me because on my old computer (WINXP), the manufacturer and the name appears on the device manager whereas in W7, nothing appears.
I didn't see that it was the same for other devices.

Thanks, It's ok for me,

Fabrice
