I got the new build together and posted it to that same thread: Librem Mini v1/v2: Feedback request for USB tuning preview build - #2 by jonathon.hall
@zstocs If you are able to get a booting OS on your Mini v2, I would appreciate it if you can try that build and let me know if the USB 2.0 connectivity is improved on the blue ports. If you are not able to get a booting OS or would like to discuss any other ways to solve the problem, please contact support.
