I don't know if I understand it right.The issue is with dropping
power... Mine is holding power right:

usbconfig 
ugen1.1: <0x8086 XHCI root HUB> at usbus1, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.1: <0x8086 XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.2: <Chicony Electronics Co.,Ltd. HP HD Camera> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
ugen0.3: <CYCPLUS ANT USBStick2> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
ugen0.4: <vendor 0x06cb product 0x00df> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
ugen0.5: <vendor 0x8087 product 0x0026> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
ugen1.2: <Realtek USB 10/100/1000 LAN> at usbus1, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=ON (72mA)

I am attaching the usbdump -d 1.2 when it stops working.
