WinCE 6.0 : USB Virtual Comm

Hi All,
I have to programmatically detach and re-attach an USB modem.
The driver creates 8 virtual comm ports.
When I physically attach it to the USB port, virtual ports are createn in
the correct sequence.

If I detach all ports calling DeactivateDevice(), and I attach again calling
ActivateDevice(), the ports are created with a different order, with
generation of exceptions.

Any suggestion?

Thank you in advance

Paolo
