Looks like USB to Serial devices based on CH340 do not work.
I found this datasheet https://cdn.sparkfun.com/datasheets/Dev/Arduino/Other/CH340DS1.PDF
FreeBSD seems to use this driver when I plug it into my rasberrypi: https://github.com/freebsd/freebsd/blob/f6abce8e79ecc1992d2d0b2e53f8e92ab3102671/sys/dev/usb/serial/uchcom.c

Could not find any better datasheets but I did find the source on OpenBSD

We do seem to reference the CH341 variant which seems to have the same driver on *BSD.

After some back and forth on IRC, it looks like it indeed needs a new driver as the above file is just a vendor/product list.
A usbser client most be written: https://code.illumos.org/plugins/gitiles/illumos-gate/+/master/usr/src/uts/common/io/usb/clients/usbser
Comparing some existing devices and the openbsd/freebsd driver, I don't think this is something I can do.

- File backup_vendor_1.patch backup_vendor_1.patch added
It's a really horrible chip, I've given up on it after poking it on and off for 3+ months.
Mostly succeeded in getting the stick to lock up and needing 5-10 min of no power to recover.
Attached is the latest backup that does not brick the stick, in case anyone in the future comes looking for it.
It doesn't do mutch aside attach.

Latest version of what I have, I'm struggling with the initialization.
