USB COM Port mess
I had an Arduino UNO happily connected to my COM3 port via a USB hub. Last week, I needed to install a FTDI USB-UART adapter and had problems with its drivers. Eventually I got it going.
Now here's the problem- whenever I plug in my Arduino, Windows thinks its the USB-UART adapter and assigns COM3 to it. I've tried updating the Arduino driver but Windows doesn't see it (thinks its a UART now?). I've tried deleting and reinstalling but the Arduino still shows up as the UART.
How can I get back to where I was, with the Arduino happy again?! Thanks,

My previous post wasn't too clear so I thought I would update with what I'm seeing.
On start-up, my only connected USB devices to my laptop are a mouse/keyboard and a hub. The laptop functions perfectly and Device Manager is fine. I have 2 additional USB devices that need to be connected:
A: which is a Arduino UNO and
B: which is a USB/TTL UART adapter.
When I connect A, the Device Mgr shows it as the UART device (device B). When I connect B, Device Mgr shows it as USB Serial Device (COM4) (device A). I can't update the driver for either because Windows doesn't see the correct driver ie. if I go to the Arduino driver folder to load the proper driver, Windows will not load as it's looking for UART drivers. It's as if the 2 devices have switched identities.
Can I "delete" this devices from the registry somehow and start over? I've tried deleting the devices using Device Manager but when I re-connect them, they assume their old identities.
I'm quite stuck on how to further troubleshoot or come up with a potential fix. Any help would be appreciated!
