I have several PS4 and PS5 controllers connected through bluetooth on my Ubuntu 23.04 Server, kernel 6.2.0.
I'm trying to build a UDEV rule to rename them, because by default they're all called "Wireless Controller".
So first of all, here is the udev chain while one of the devices is connected :
$ udevadm monitor --environment --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

This is a DualShock 4 controller, there are a lot of subdevices (touchpad, sensors, leds), the one I'm interested in is the following :
/devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005/input/input22
That's the one that actually handles the front buttons.
So I built the following rule
ACTION=="add", SUBSYSTEM=="input", ATTR{uniq}=="90:fb:a6:e0:4f:6b", ATTR{name}="PS4 Anniversary"
But it fails with this error :
input22: /etc/udev/rules.d/98-pads.rules:2 ATTR '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005/input/input22/name' writing 'PS4 Anniversary input'
input22: /etc/udev/rules.d/98-pads.rules:2 Failed to write ATTR{/sys/devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005/input/input22/name}, ignoring: Permission denied
Permission denied, I believe that's because the given file /sys/devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005/input/input22/name is read only (-r--r--r-).
Just to test, I edited the permissions and tried again, this gave me "Input/output error". This looks like not writable data, so I think it is inherited from a parent.
Now I'm trying to work with the parent device /devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005 here is the available "udevadm info -a" :

But I don't really understand, for instance "udevadm info /path/to/device" tells me there are properties like "HID_UNIQ" that would allow me to match the device, but they are not in "udevadm info -a" and I can't make it match in the rule, I've tried the following but none of them worked :
ACTION=="add", ATTR{hid_uniq}=="90:fb:a6:e0:4f:6b", ATTR{hid_name}="PS4 Anniversary hid"
ACTION=="add", HID_UNIQ=="90:fb:a6:e0:4f:6b", HID_NAME="PS4 Anniversary hid"
The rule is never triggered, which means at least the matching part is not working.
I noticed a "uevent" file that is writeable in that device folder :
-rw-r--r-- 1 root root 4096 May 18 22:35 /sys/devices/pci0000:00/0000:00:14.0/usb1/1-10/1-10:1.0/bluetooth/hci0/hci0:256/0005:054C:05C4.0005/uevent
The content of that file should allow me to match the device usign its "uniq" address and rename it so it might be propagated to children devices :
DRIVER=playstation
HID_ID=0005:0000054C:000005C4
HID_NAME=Wireless Controller
HID_PHYS=f4:ce:23:f7:16:91
HID_UNIQ=90:fb:a6:e0:4f:6b
MODALIAS=hid:b0005g0000v0000054Cp000005C4
Can this uevent file be used through udev rules ?
Maybe I'm trying too hard and there is a more straight forward way to rename a bluetooth device ? Well, even if that's the cae I'd like to understand what I can or cannot do with udev rules...
Cheers
