Is that LEGO First? My son was involved when he was younger, and I worked with a team about ten years ago that was sponsored by my employer. An amazing program.

Itās FIRST Robotics Competition (FRC) which is the high school level. FRIST Lego League (FLL) is at the elementary and middle school level. And yeah, itās a great program. Great to see students get excited about academic/technology challenges.

Yup! Same program. My son participated through middle school, mostly to humor me, I think. Heās graduating high school this year and is interested in history, psychology, and teaching, not math/science/engineering. Heās social, outgoing, and musically inclined. Weird how different kids can be from parents.
I wish your team success in the competitons!

I seem to get that same COM-4 message no matter what I do.

So I installed the driver linked above before I got my keyboardā¦ Device Manager shows Keyboardio Model 01 (COM7). I used driverquery from the cmd prompt to see that the device drive really was installed, since as noted Windows gives no feedback.
I had pulled from master, and updated plugins, which may have been a mistake. Iām generally pretty comfortable with git, but havenāt previously used submodules, so I may be doing something wrong there. Running āVerifyā on Model01-Firmware.ino gives me this:

Thank you for your patience and persistence.
I know this is super frustrating and disheartening to work through, but it will be worth it. I was a PVT user and it took me about a month to get things working for myself, so Iāve been there. Having it all working now, and being able to change what I want the keyboard to do more or less at a whim has been a game changer.
I am certain that Jesse will see this through and make it all right for you. Iām sorry itās harder than anyone had a reason to expect.
Just in case, I tried checking out v1.19, and get the same problem when trying to flash, but this one doesnāt have the error with numlock.
(The numlock issue is version skew between Kaleidoscope and. the Model 01 Sketch)

I figured it was something like that, which is why I wasnāt too worried about it.

I tried turning off my firewall. I thought it was worth a shot but i donāt think it helped.
Here are some additional possible fixes:
And, uh, I was wrong. Apparently some Windows firewall software does meddle with serial ports. I had no idea.

Iām getting the same issue despite installing the above keyboadio driver first. My Keyboadio shows on COM5 in Device Manager, and my Arduino IDE is set to COM5. Neverthe less, I get
avrdude: ser_open(): can't set com-state for "\\.\COM5"
I tried temporarily turning off the Windows Firewall (not to be confused with MS Essentials mentioned previously which is Antivirus), but still got the error.
@jesse - are you testing on a 32-bit or 64-bit Windows 7 install? Not sure if it plays a factor, but I want to track down any differences between your success and our failures. Iām running 64-bit version. What about you @Gaye and @kajsa.anderson? 32-bit or 64-bit?

@Javaru Windows 7 Ulitmate SP1 x64, patched up to current, accepting all Microsoft defaults, but with no third party software other than the Arduino IDE. Windows is not activated, though it worked on the previous build, which was.
If there are windows diagnostic tools I can run that will give you a fuller picture of my system, Iām happy to run them.
OK, that matches me at a high level.
Not easily. You basically need to look at all the patches and see which are installed.
In Device Manager, is your Model01 on COM1? While Iām not seeing it specifically spelled out as such, it seems all the posts I find on this issue, people have the Arduino on some COM port other than 1. And some of the proposed solutions seem aimed at, or at least end up with, getting the Arduino so it is on COM1. And although we are selecting the COM port in the Ardunio IDE, I canāt help but wonder if thereās an issue there. Iām going to fire up my laptop and see if it has any other COM ports in use and try flashing it from there.
Iām also running 64-bit and itās COM-4.
I have already gone through this one when I was googling the problem a few days back. It was frustrating because their problem seems so simple and has a workable solution. It doesnt work for me, since its a different kind of problem, ie a wrong arduino config.
Right now, I am wondering why everyones error message is different from mine. Got a bunch of new usb c cables today, will try them out.
Edit: I will also try disabling my Windows firewall.
Also @jesse: what was the actual error you reproduced when you were testing it on win7? We seem to have uncovered two problems, com-state and missing file, which may or may not be related.
I was seeing the missing com port issue. I havenāt reproduced the other one.
