 Basically what happens here is that kernel USB driver knows about power off,
 but doesn't send notification about it to udev.
 
-You can find workaround for this issue in [this article](https://goo.gl/qfrmGK).
+You can use this workaround for this issue:
 
+    sudo uhubctl -a off -l ${location} -p ${port}
+    sudo udevadm trigger --action=remove /sys/bus/usb/devices/${location}.${port}/
+
+Device file will be removed by udev, but USB device will be still visible in `lsusb`.
+Note that path `/sys/bus/usb/devices/${location}.${port}` will only exist if device was detected on that port.
+When you turn power back on, device should re-enumerate properly (no need to call `udevadm` again).
