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 |
