It may be possible to send the request to the hub from userspace, but
I haven't tried it.
Older Windows Version (before Vista) had IOCTL_USB_HUB_CYCLE_PORT
to perform a power cycle. I think there is still a way in newer
version too, If I am not wrong the WHQL driver testings tools
do perform USB power cycles frequently when testing USB devices.
Of course the above is only relevant if you care about Windows ;-)
Best regards,
Dieter
