RPI3, usbconfig: could not open device: No error: 0

[bob prohaska]

While trying to unstick a pl2303 usb-serial adapter that wasn't
showing up on a Pi3 I tried

root at www:/home/bob # usbconfig reset
usbconfig: could not open device: No error: 0

That seemed odd, so I tried:
root at www:/home/bob # uname -a
FreeBSD www.zefox.org 13.0-CURRENT FreeBSD 13.0-CURRENT r349799 GENERIC  arm64
root at www:/home/bob # usbconfig
ugen0.1: <DWCOTG OTG Root HUB> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen0.2: <vendor 0x0424 product 0x9514> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (2mA)
ugen0.3: <vendor 0x0424 product 0xec00> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (2mA)
ugen0.4: <vendor 0x413c product 0x3010> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)
ugen0.5: <Logitech Logitech USB Keyboard> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)

which looks quite normal.

IIRC this is the first time I've tried the "usbconfig reset" command,
so I've no baseline for what to expect.

The machine has been reverted to r349799 for sanity
checking, if the behavior is correct or fixed please 
accept apologies for the noise. If it's wrong is it 
worth a bug report?

Thanks for reading,
