I am having many issues. My vision sensor won’t connect and I cannot do anything with it. Also my brain has severe problems with connecting to my brain. I can’t compile code.

Please take the time to provide a more detailed question, so we are able to help you.
We can’t know what your problem is if we don’t know what you have tried.
Do some research and find guides from vex on how to use the vision sensor.
You don’t need brain to compile. You get compile errors if you do something wrong in your code. What are your problems with connecting to the brain?
Again, you need to ask better questions with more information for us to help you.

I know how to use a vision sensor. My vision sensor will not connect to the utility. I’ve switched sensors, brains, cords, and computers. My vision sensor just will not work.
For the brain, my brain has trouble connecting to the computer and I can’t download code onto the Brain.
We had started troubleshooting in this topic
One thing you could try is using a USB 2.0 powered hub between computer and vision sensor. I have seen situations where some laptops are not able to provide enough power for the vision sensor. Beyond that, not sure what to suggest, all the usual ideas, such as changing cables, you have already tried.
I am having the same problems. Was a solution ever discovered?
I’m hitching on to this thread, as it appears to be the closest (non-closed) thread to my situation.
We have two (non-AI) vision sensors that worked previously. We’ve been trying to configure them again, but neither is now recognized by the Configure utility. (Connected to a laptop using codev5.vex.com.) No image is displayed by the utility.
When the sensor is connected to a brain using a smart cable, the brain does display signal, so I’m confident the sensor itself is still operational. This is true for both sensors.
I saw a mention somewhere (don’t recall if it was the forum or the knowledge base) that the sensor firmware could be updated by holding down the button while plugging in the USB cable, so we tried that, but that made no difference. Nor do I see a way to read out the sensor firmware version.
I’ll try to locate a powered USB hub as jpearman suggests, but would be grateful for any other clues or experiences.
Thank you!

Three year old topic, please start a new one next time.
codev5.vex,com has minimal implementation of the vision utility that does not show streaming images, did you press the capture button top left ?

Yes, I saw the age and noticed that the thread wasn’t closed after a year of inactivity as is the norm (which suggested it was still fair to post). And the response said the new post would float the thread back to the top. Anyway …
Yes, we did. It reported there was no device found.
Out of curiosity: Is the VEXcode vision sensor configurator now set up for the AI vision sensor, and is that interface different in some way that would affect the original vision sensors?
We’re pretty much stuck with using codev5. Our student laptops are administratively locked down; we can’t install or update local copies of VEXcode, and so every time there’s a revision, the local VEXcode loses the ability to work on code written with earlier revs. (This was the subject of my first post to vexforum; you may recall you helped me with a one-time workaround.)
In addition to a powered USB hub, I will also try bringing in a personal laptop with a local copy of VEXcode, and will report back. But these solutions, even if successful, don’t really scale.
Thank you!

What PC (Mac, chromebook, windows) are you using ? I forget, but a driver may be needed under windows. To be honest I didn’t even realize we had released the web version, I’ll check and see if windows needs a driver next week, unless @rbalasub knows.
New configuration utility that’s part of VEXcode, create an AI Vision device in codev5.vex.com and you can see that (but not use it unless you have the new sensor)

Windows. (And if a driver is needed, we probably still won’t be able to install it, because we’re locked down.)
Ah, I didn’t think to look for a separate AI VS in the device list when we were at the bench; the question just occurred to me as I was posting. I assumed facts not in evidence 
.
Thank you!

Follow-up from testing today:
The vision sensor calibration worked on a Mac.
The vision sensor calibration did not work on Windows (neither local VEXcode nor codev5.vex.com), not even in freeze frame, not even with a powered USB 2.0 hub. (Notably, it did work a couple of years ago on some older Windows laptops and an older VEXcode version.)
Does it show in the windows device manager ?
Windows does need drivers for the vision sensor, VEXcode should have installed those, but I believe the ones here may work also.
