I have a similar problem and tried:

root%asus.immnet.dk@localhost:/root # drvctl -l uhub5
uhub5 ulpt0
uhub5 uhub8
root%asus.immnet.dk@localhost:/root # drvctl -s uhub5
drvctl: unknown option -- s
Usage: drvctl -r [-a attribute] busdevice [locator ...]
       drvctl -d device
       drvctl [-nt] -l [device]
       drvctl [-n] -p device [prop]
       drvctl -Q device
       drvctl -R device
       drvctl -S device
root%asus.immnet.dk@localhost:/root # 

Is the switch you are suggesting a typo?
Or am I using the command incorrectly?

Kind regards
