Still playing with `usbdump -s` values to get a reasonably-sized dump.

In the meantime, I set hw.usb.muge.debug=1 and uploaded a segment of
/var/log/messages during a period where the interface was flapping under heavy


A tip from the motherboard vendor was to disable USB power saving as the hubs
can behave poorly with that enabled, but `usbconfig ugen0.1 power_on` throws an

# usbconfig -u 0
ugen0.1: <Generic XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps)
pwr=SAVE (0mA)
ugen0.2: <Microchip LAN7800> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
# usbconfig ugen0.1 power_on
usbconfig: could not set power ON: Invalid argument

Is there another way I can try that while I'm still tuning the "usbdump -s"
