It is a bit easier to read than the ktrace output. Here are the bytes received,

Solis not detected! aborting ...

I highlighted the final character (0xfe/254). It seems as though the code
expects the serial stream to always put the 0xfe character at the end of the
buffer, but as you can see, that is not the case in the debug output. (The code
loops twenty times, so it is not impossible for it to sync: this may be what
happened when you ran the driver in gdb.)

We could modify the code to re-sync with the start character, but what concerns
me is that a byte gets dropped occasionally. If you run "stty -f /dev/cuaU0
raw", then run the driver with the same debug flags, do you get the same
sort of output, where the "fe" character moves left? You might also
try unplugging the USB cable, then running the driver immediately after plugging
it in again (maybe there is a buffer filling up - that happened a number of
years ago on another USB interface on FreeBSD).

[Nut-upsuser] APC BACK UPS 2200 model BZ2200BI-BR (update)

Turns out another user reported the same issue with a slightly different model:
https://github.com/networkupstools/nut/issues/231
<https://github.com/networkupstools/nut/issues/231>

The "stty -f /dev/cuaU0 raw" trick should help, but I am confused as
to why FreeBSD has different "raw" settings than what is set up at the
same time as the baud rate:
https://github.com/networkupstools/nut/blob/master/drivers/serial.c#L163
<https://github.com/networkupstools/nut/blob/master/drivers/serial.c#L163>

Before running "stty raw", can you please send the output of
"stty -a -f /dev/cuaU0"?
