Thanks! Glad to see people wanting to try this out. We will be releasing beta firmware This is still without USB. Our goal is to get user feedback and testing for everything else first. Since we changed so much under the hood, we want to be sure that motors and sensors are working as expected. It does already include 5 code slots, which will be the biggest visible change. The next beta after this is expected to include USB for SPIKE, as well as EV3. Users like yourself who have been waiting patiently can request a link to try it sooner. We will publish this once it is stable enough to get a good user experience for most users.
A scenario similar to this but adapted for USB will work once we release a version with USB support. |

I am also interested in trying to using the newest Pybricks with my EV3s. A couple of weeks ago I found the labs.pybricks.com website. I was able to retrieve a nightly build and install it onto one of my EV3s using the USB connection. All I get is the Pybricks logo and the ability to move the small black square left or right. Today I see that I can install the firmware without getting the nightly build. I still only get the logo and the small black square. How do I connect the EV3 so that I can test some programming using the new Pybricks? I tried using the labs.pybricks.com website. The program sees the EV3 using the USB connection, but there is no EV3 hub in setup. |

We are using spike prime. Any pointers on building a custom firmware?

Prime, you will need to do a custom firmware build with USB enabled.

Checked the EV3 set examples and to keep that lot of updates off pybricks, made a separate repo for myself to keep my progress: Next the syntax against the V2 doc. End target there is to copy the end result (after the EV3 beta release) to make a doc discussion in pybricks repo. |

Looking over the release notes for pybricks 4.0.0b1 (and b2), and it sure looks like you guys have been busy! Well done! I haven't tested anything yet, but believe me, I will! I was wondering if you can explain a little more about the USB connectivity. Since this release is for pybricks, and not pybricksdev, I think this will just be USB comms for running programs? Like if someone wanted to connect a hub to a PC and have them communicate back and forth? This would not have anything to do with uploading programs to the hub?
