For my next project, it would be useful if I could configure my STM32 to be a composite device, providing both RS232 (COM port) and Mass-storage.

I recall that with Win2000, the standard driver would not allow COM ports to be part of a composite device.

Does anybody know if this has changed with WinXP / Vista / Windows 7?

Has anybody tried it?

Thanks,

Chris.

try:

svn checkout

The CDC+MSC firmware is under dongle/firmware/Projects/CDC.

You can compile it using IAR EWARM 5.40 KS or Codesourcery GCC.

See dongle/firmware/readme for more information.

As I know, W2K doesn't support IAD, but WinXP and Ubuntu 8.04 supports well.
