USB Function Vendor adn Product ID problem

Hi,
I have a problem with my USB Function Driver. I have a BSP cloned from the
Mainstone III. I Use the USB Function without any changes, selection the
RNDIS version.
All have worked fine for some months, but now i made some change to my BSP
and i get an error.
When i Plug my USB cable into the PC i can see a device connect but its
Vendor ID and its Product ID are both 0.
I put this vendor and product ID into the register
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\RNDIS]

During Runtime i can check the register and see this values.

I would like to find the source code where Windows CE send Vendor and
Product ID to the PC so i can find why it doesn't read any value (i suppose
0 is a default value).

Anyone know where I can find this source code? Otherwise, what should i
check in order to find my problem?

Regards

Rudy

Hi Ruby,

the sources of the RNDIS driver are at wince600\public\common\oak
\drivers\usbfn\class

Do you get a "Unkown Device" on your PC? I think a 0 is set by the PC
when he cann0t identify the connected device correctly.

regards,

Mike

For me that sounds that something is wrong in your USB device (function)
driver if you get unknow device on the PC side. Did you change anything
in that driver?

I have an old version (before Windows CE Update of April 2007) that works
and the source code is the same.
I have only work with Vendor Id e Product Id.

Have you uninstalled the USB device on your PC and inserted the cable
again? What happens when you reset teh PID/VID in the registry?

I have reinstalled my PC

What happens when you reset teh PID/VID in the registry?

When i change VID and PID in my device nothing happens. PC Side i haven't
change anything but I tried to connect the USB Cable to my laptop with the
same result.

Check all the changes you made to the BSP as something obviously broke the
USB function support. This could be memory maps, GPIO pin configurations or
Interrupt handling among many other potential issues.
