kernel panic avrdude, usb related?

Hello, Fresh install of 5.4, pkg_add avr, avrdragon programmer plugged in via usb, invoked `sudo avrdude -c dragon_isp -p attiny4313 -P usb` causes the machine to panic. Tried different avrdragon programmers same thing. Tried bsd.sp and bsd.mp same thing. Perhaps unrelated but my /etc/motd
