 MSComm with Serial Port on USB

Has anyone had any experience using MSComm with a serial port on the
USB?

I have a Belkin Serial Port adapter which plugs into my USB port.
When I do MSComm1.portopen = true it hangs my whole system and I have
to reboot.

Hi,

Do you have error handling in place?

On Error Resume Next
If MSComm1.PortOpen = False Then MSComm1.PortOpen = True
If Err.Number > 0 Then
    MsgBox "Error opening port: " & Err.Description
End If

If this doesn't work, I'd contact the manufacturer of the adapter.  MSComm
simply wraps the Windows communications API, so any lockup would have to be
caused by outside problems (the USB driver, probably).
