Presumably, you client is paying you to get this to work?

What portion of that fee will you be sharing with forum the member(s) who help you to get this going...?

I need to get the virtual comm port working. I have a IAR STM3210B - SK evm. I connect the EVM and the pc sees the device and I cancel the new hardware manager as the Virtual comm port install says to do, then I continue the comm port install but it does not add a virtual comm port. It has the device as a unknown device with no driver. The device is called CD Class.

I need to know what SW to program the evm and what I need to get the comm port working.

1) I have a IAR STM3210B - SK EVM loaded with the example workspace called IAR-STM32-SK and project titled virtualcom loaded to flash on the EVM. The LCD message says it is this project.

2) Using the VCPDriver_V1.1_Setup from ST website.

3) Windows XP with latest updates

I connect the EVM and the pc sees the device and I cancel the new hardware manager as the Virtual comm port install says to do, then I continue the comm port install but it does not add a virtual comm port. It has the device as an unknown device with no driver. The device is called CD Class.

What SW from the ST site or where ever should I use to program the EVM and what else do I need to do to get the comm port working.

I do not have any problems with the STM32 programming its all in the Virtual Comm Port install. I do not have a CATC or other USB debug HW. I have used other USB devices and their drivers loaded with no problem on other devices.

Of course - but it seems a bizarre thing to put in your opening post:

As if that should give your request higher priority; or as if others don't have employers and/or clients for whom they need to get things working.

Maybe it just lost something in translation - if so, I apologise.

Anyhow, what, exactly, have you tried so far?

Are you using a standard ST example or app note? If so, which one(s)?

Are you using something from IAR? If so, what - and have you asked IAR?

What debugging have you done on the target?

What (if any) tools do you have to monitor what's happening on the USB wires and/or in the PC?

Actually I am the developer.

@John-

I duplicated your ''failure to install VCP'' on 2 WinXP SP3 machines. (replied to your tech spt. post)

To assist me/others - it appears that you changed the source code on your IAR Eval board (can't see how you would modify the VCP

I have it working. The clue was the CD class device name. The Virtual Port Comm wants it to be a different designation. I used a code example from ST for the STM32, modified it to work with the IAR EVM and it configured the virtual comm port. This is not documented anywhere I looked. Hope this help some folk in the future.
