Thanks for your suggestions. I don't think that adding a second interface is going to help.
My current testrun has over 60 million back-and-forths at 1000 per second, and my client is using about 10x less. -> we're not running into problems here. (back-and-forth: I had "echo on" so each character was echoed back to the host. I've now turned "echo off" so now I only get the 1x per second asynchronously injected extra command which DOES produce output. My client uses echo off of course. His program knows what it sent.).
He has now confessed that he's turning on some powerful 230V equipment that is physically nearby. Apparently that causes the USB connection to go burp, that Linux no longer sends or at least the RP2040 no longer receives the stuff the applications try to send.
Do you happen to know a howto that explains what to do to get the dual CDC interface? This was in the demo for a recent chibios. I've switched to RP2040 a couple of years ago, but now I'm working on a project that DOES use chibios on STM again, and I'm happily using that feature. I haven't googled yet. Maybe I should. ... OK. I did. Not really a clean example for pico found. Might be possible to piece together from various other examples. If you know a good example, I'd appreciate it if you'd let me know.
