 Compatible USB hubs
 ===================

-Note that very few hubs actually support per-port power switching.
+Note that not many USB hubs correctly support per-port power switching.
 Some of them are no longer manufactured and can be hard to find.

 This is list of known compatible USB hubs:

@@ -186,20 +255,35 @@ Linux USB permissions
 =====================

 On Linux, you should configure `udev` USB permissions (otherwise you will have to run it as root using `sudo uhubctl`).
-To fix USB permissions, first run `sudo uhubctl` and note all `vid:pid` for hubs you need to control.
-Then, add one or more udev rules like below to file `/etc/udev/rules.d/52-usb.rules` (replace 2001 with your vendor id):

-    SUBSYSTEM=="usb", ATTR{idVendor}=="2001", MODE="0666"
+Starting with Linux Kernel 6.0 there is a standard interface to turn USB hub ports on or off,
+and `uhubctl` will try to use it (instead of `libusb`) to set the port status.
+This is why there are additional rules for 6.0+ kernels.
+There is no harm in having these rules on systems running older kernel versions.

+##### Raspberry Pi 5

+  Raspberry Pi 5 has two USB2 ports and two USB3 ports (total 4).
+These ports are connected to 4 distinct USB hubs `1`,`2`,`3`,`4` in really weird configuration
+(but depending on OS and HW revision hubs of interest can be `2`,`3`,`4`,`5`).
+If USB3 device is connected to blue socket, it will be detected on USB3 hub `2` or `4`.
+If USB2 device is connected to any socket or USB3 device connected to black socket,
+it will be detected on USB2 hub `1` or `3`.
+Regardless of USB2/USB3 connection type, blue sockets are always port `1`,
+and black sockets are always port `2`.
+
+  Each of 4 USB onboard hubs advertises as supporting per-port power switching, but this is not true.
+In reality, Raspberry Pi 5 all 4 ports are ganged together in one group,
+despite belonging to 4 different logical USB hubs.
+
+To turn off VBUS power it has to be disabled across all onboard hubs and ports with:
+
+   ```
+   uhubctl -l 2 -a 0
+   uhubctl -l 4 -a 0
+   ```
+
+To turn it back on:
+
+   ```
+   uhubctl -l 2 -a 1
+   uhubctl -l 4 -a 1
+   ```
+
+Note that VBUS power goes down only if all ports are off -
+enabling any single port enables VBUS back for all 4 ports.
