Thank you for your .inf file and the screenshots. I tried the inf file immediatly on my Vista, but the same Code 10 error is happening. Am i doing something wrong wirhin the code ?

I'll try to debug the code and hopefully i find the problem.

Hi bsmisl,

Here you go : new Driver ''stmcdc.zip'' which contains only one .inf file compliant with all Microsoft Windows Operating system so far including Windows 7 ( either x86 or x64 ).

For full proof, I have attached the Screen shots that show that it is working properly with

Windows 2000

Windows XP

Windows Vista (x86 and x64)

Windows 7 (x86 and x64)

Enjoy it

Hello,

About the Code 10 error, i found nothing usefull, my device is still not working under Vista or Win7. I think it might be something in the code. I have done some USB sniffing with the SnoopyPRO but i do not know if any thing is wrong. Has any one have the sniffers log, from the Vista or Win7 ?

I hope i find something to fix this.

Thanks,

b

Good day,

I got it to work on all OS.

The problems were in the buffer sizes, that i fixed and it all works like a charm now.

Well, thank you all for help,

Greets,

I've the same issue. If I don't set buffer size to 64, I get error 10 in Windows. Is this normal? There's a way to use a greater buffer?
