Composite USB Virtual COM port and HID keyboard on Windows 7 - Please help!

Dear All,

I made a composite USB with Virtual COM port and HID keyboard. It works fine on W2K/XP/Ubuntu, but it does not work on Windows 7. I've tried everything, but nothing works (This device cannot start. Code 10).

To make things worse, Windows 7 is too dumb to recognize the HID keyboard, which does not happen in XP/2K (they recognize the HID keyboard, even without a CDC .inf).

Please help.

Thanks in advance.

Are you using your own drivers, or strictly stock drivers? Code 10 means
that the driver returned an error code while it was starting up.

Windows 7 is much pickier about the USB spec compliance than previous
versions. Is it possible your descriptors are not quite correct? What DO
you see on Windows 7?
