Specifying COM Port emulated by USB to Serial Convertor

I am trying to provide a serial connection to link my Psion Series 5
to a laptop which has no native serial ports (it does have an internal
modem "on" COM2). I have a USB to serial adapter that installs as COM5
(with no options to change this in the install dialog or driver
properties), but the link software does not "see" it - presumably
because it is not a "real" COM Port. I suspect that if the adapter
were on (say) COM1, which is otherwise unused, it would "just work",
since COMs 1-4 are presented as connection options by the link
software even though only COM2 actually exists, and the "working" code
is probably less hardware-dependent than the code that is supposed to
find available COM ports. Is there a potential Registry tweak that
might be able to force the USB device to use COM1
Please respond to the Newsgroup, so that others may benefit from the exchange.

Thanks to Dirk Straka in comp.sys.psion.misc, this is now sorted. It
turns out that PsiWin (the link software) does recognise the existence
of the USB serial port (and uses it happily) if the system is rebooted
with the USB serial adaptor connected.
