Other RP2040 boards • Re: Using board with or without USB attached - freezes when USB not attached

Hi hippy

Thank you for your reply.

After further testing I found this to be a non-issue.
I was running this test on several boards at once.
By coincidence, the issues occurred in the ones I did not have a USB connected to, but in reality, they seemed to be caused by a mismatch in length on TX+/TX- and RX+/RX- lines.
There were reversed in the board so I had to cross them over using enamelled wire but I guess there was too much mismatch in length in some of them, which just happened to be the ones without USB.
Redid the fix taking more care to avoid mismatch in length and the problem stopped occurring.

I wrote print but am using C.
Thank You
