Tried two different RP2040s with no change (one is an RP2040W original, the other is a Pimoroni Plasma 2040W).
Using the latest HyperHDR v20beta and HyperSerialPico
HyperHDR set with rp2040 handshake, and to ttyACM0.
The only thing I can see is that ttyACM0 is linked to cdc_acm 7-1:1.0. But based on lsusb, it should be 7-1:1.2?
