USB Low speed Device mode on RP2040 possible?

[mengstr]

Is it possible to force TinyUsb for RP2040 to be a USB Low speed device? I basically just want it to enumerate as a Vendor class. I can't find much handling of LS in the code, and the change logs only mentions being a host and accepting HID hardware. So before I dive in too deep here I'd better ask. ;-)

This is to capture traces of the D+/D- for a complete enumeration so I can use that as input in a Digital logic simulation. My end goal is to make a simple USB interface in 74-series logic ICs, no CPU, no USB controller. The hardware as it is now can take a packet and detect SOP, EOP, handle the bit stuffing and verifying the two kinds of CRCs used so it's time to start working on making it handle the enumeration and message flows.
