It's a non-debug build of ulpt, so that doesn't exist:
sysctl: unknown oid 'hw.usb.ulpt.debug': No such file or directory

After unplugging the HP:

root at pi:/home/george # usbconfig
ugen0.1: <OTG Root HUB DWCOTG> at usbus0, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=SAVE
ugen0.2: <product 0x9512 vendor 0x0424> at usbus0, cfg=0 md=HOST 
spd=HIGH (480Mbps) pwr=SAVE
ugen0.3: <product 0xec00 vendor 0x0424> at usbus0, cfg=0 md=HOST 
spd=HIGH (480Mbps) pwr=ON
ugen0.4: <Lexmark E120n Lexmark International> at usbus0, cfg=0 md=HOST 
spd=FULL (12Mbps) pwr=ON

I attached the usbdump output, though there seem to be quite a few
packets not connected with ulpt burying the interesting packets in
the noise.                                                 -- George
