@Xusia What is is you’re trying to do? A firmware update? If so, is it for a specific feature of the new firmware? I have seen this before:
If your simply looking to change some settings, I think it’s pretty straight forward having looked into it a bit a playing around with the software. Phsicaly it should just be USB port on your windows machine to the USB port on your (master ) VESC. I have seen some reports of issues connecting with a USB 3.0 port and directing users to use USB 2.0, but that seems strange. Hopefully it isn’t a problem because the only machine I have with a USB 2.0 port is an Nokia Booklet from 2010, and it’s freaking slow. I don’t yet have the ability to physically connect as I’m waiting on my right angle adapter. I started a thread related to Raptor specific VESC programming. Maybe you could post more specifics about what you are looking to accomplish, or difficulties your having, there.
Edit. I don’t know whey this didn’t show as a reply. Edited to add the @Xusia to the top.
