My Flex Control is working.
Buttons, Tuning Dial
but I have a strange question
I USED to have it connected on com48, up high and away from any other ports.

First let me say it had been unplugged for a while as I was changing some things around.
I plugged it back in (into the computer), and although I expected a hastle, it worked.
Dial, buttons, the whole schlameil.

In Device Manager it's listed as com 13 and the Driver is listed at FlexControl USB Control Knob (Com 13)
What's confusing is...I never created a Com 13. (What Ham is going to trust his rig to the possibility of the Number 13?

I don't normally shy from Triskaidekaphobia.

But how did this happen?

I'm not going to touch it....but if anyone can make a guess as to why, or how this happened, please let me know so I can cancel the exorcism!
Those cost more than a new Alpha!

Until then, I'll just use it as it is and hope for the best.

Welcome to the world of USB serial device enumeration on Windows!

Both virtual and USB serial connections are handled differently than physical serial ports on Windows.

Each time you plug the FlexControl into the computer on a specific port, Windows will assign a new serial port id to the device depending on what other devices have been enumerated in the system.

So if you unplug, then replug the device into a different USB port, or if in the meantime, another serial port is added to the computer (virtual, another USB, physical), Windows will create a NEW com port for the device the next time its plugged in.

What will work (most of the time) is to assign the FlexControl when plugged into a specific port, to a COM port that is way (way!) above all currently assigned ports.  Usually, this will work when you pluf the FlexControl back into the same physical USB socket.

Sorry this is such a hassle - its one of the black magic areas of Windows and has to do with how Windows tracks the available COM port numbers (which don't track USB or virtual ports).
