It should be noted that this issue does not affect just the
FlexControl. This problem can hose up any USB/Serial device that is
connected to the PC once virtual serial ports are defined.
Also as Stu pointed out, once the FlexControl is installed and properly
configured, you can go into the Windows Device Manager and change it's
com port assignment to a different comport if you need to move it out of
the 1-8 com port range to deal with third-party programs that are
deficient in available com port assignments.

Hi Tim,
This is a good Heads up.
Anyone with the N1MM logger will need this information, as it only supports
the first 8 com ports.
Thanks for the Information& work around.

Subject: [FlexEdge] Future FlexControl users - Installation heads up
To all Flexers who have purchased the new FlexControl tuning knob
Since the FlexControls are now shipping in volume and will start showing up
at your QTH shortly, there is an installation consideration you should be
aware of if you use VSPmanager for virtual com port access.
There is a bug in the Eltima API used in VSPmanager that results in the
possibility of the FlexControl's assigned physical com port to conflict with
an already defined virtual com port resulting in at worst, a Windows crash
(BSoD). There have also been reports of other virtual com port software
causing issues too, so this condition is not exclusive to VSPmanager.
This information is in the FlexControl errata that is included with the
FlexControl, but I thought it would be useful to provide a proactive notice
for those who might want to take action before your FlexControl arrives.
You can download a copy of the FlexControl errata using this
URL: http://support.flex-radio.com/Downloads.aspx?id=370
The issue is that VSPmanager is not properly reporting it's virtual com
ports to Windows and when the FlexControl drivers are initialized and a
physical com port is assigned by Windows to the FlexControl process, that
assigned com port is already in use by VSPmanager. Two applications cannot
have exclusive use of the same comport, resulting in the operating system
crash.
This situation arises when you have virtual comports that are assigned to
low numbered comports; such as 1-9 since that is the likely range of com
ports Windows will assign to new physical com ports.
You can mitigate this problem in two ways.
First by defining virtual com ports that are not in the range of 1-9.
So if you have virtual com port pairs defined where either of the com port
end points are in this range, delete the com port pair and re-create it with
the com port end points greater than 9.
If you have already installed PowerSDR 2.1.x, then remove VSPmanager (make
sure you delete the com port pairs first), install PowerSDR v2.1
RC3 or later, get the FlexControl working properly and then install
VSPmanager and define your virtual com port pairs. In this case, since the
FlexControl is already installed and has a physical com port assigned,
VSPmanager correctly identifies the physical comport that the FlexControl is
using and will not allow you to create a virtual com port using the com port
already in use resulting in no com port conflict.
