hidraw fest zuordnen

sralus · Dec 28th 2022

Hallo

Ich habe zwei USB Geräte die eine Hidraw schnitstelle benutzen.

Ich möchte diesen Geräten gerne eine feste zuornung geben.

Die ausgabe von : sudo udevadm info -q path -n /dev/hidraw0 ist:

/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.1/1-1.1:1.0/0003:0665:5161.0001/hidraw/hidraw0

und von : sudo udevadm info -q path -n /dev/hidraw1

/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.4/1-1.4:1.0/0003:0665:5161.0002/hidraw/hidraw1

dmesg | grep hid

Wie kann ich eine regel erstellen damit diese USB Geräte immer HID1 und HID2 bleiben ?

MFG

Ich habe mal von udev-Regeln gelesen, könnte da vielleicht etwas dabei sein ?

Hersteller und Modellnummer merken:

Quote

[root@nexus rules.d]# lsusb
......
Bus 001 Device 014: ID 1d57:0005 Xenta Wireless Receiver (Keyboard and Mouse)
.....

Dann eine udev-regel erstellen:

Code: /etc/udev/rules.d/99-hidraw.rules

ACTION=="add", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1d57", ATTRS{idProduct}=="0005", GROUP="input", SYMLINK+="my_mouse_raw"

Nachdem die Maus angeschlossen wird, wird zuerst die Gruppe input zugewiesen und dann der Symlink my_mouse_raw erstellt. Wenn man zwei mal das gleiche Eingabegerät hat, muss man schauen, ob es noch eine Seriennummer hat, mit der man die Geräte unterscheiden kann. Das habe ich damals z.B. beim tty2USB von FTDI gemacht. Ich habe zwei identische Modelle anhand der Seriennummer bestimmten Ports zugewiesen.

Hier eine Referenz: https://wiki.archlinux.de/title/Udev

Ergänzung:

Da es mich interessiert hat, wie der Inhalt von hidraw zu interpretieren ist, habe ich das mal anhand eines Beispiels umgesetzt und modernisiert.

Python

import struct


def get_mouse_event(file):
    with open(file, "rb") as fd:
        buf = fd.read(4)
        button = buf[0]
        b_left = bool(button & 0x1)
        b_middle = bool(button & 0x4)
        b_right = bool(button & 0x2)
        x, y, z = struct.unpack("bbb", buf[1:4])
    return b_left, b_middle, b_right, x, y, z


while True:
    print(get_mouse_event("/dev/my_mouse_raw"))

PS: Guten Rutsch.

@DeaD_EyE

Danke für die Antwort.

Habe genau das Problem mit den zwei gleichen Geräten.

und dann habe ich noch probiert:

Code

/bin/udevadm info -n /dev/ttyUSB* -a | grep serial
 SUBSYSTEMS=="usb-serial"
    ATTRS{serial}=="A10LSX4A"
    ATTRS{serial}=="0000:01:00.0"

 /bin/udevadm info -n /dev/hidraw0 -a | grep serial
   ATTRS{serial}=="0000:01:00.0"
 /bin/udevadm info -n /dev/hidraw1 -a | grep serial
   ATTRS{serial}=="0000:01:00.0"

Wie bekommt man denn nun die Serial ausgelesen damit ich die Hidraw1&2 geräte zuordnen kann?

Beste Grüße und Frohes neues 2023

RTFM · Jan 2nd 2023

Deine beiden identen Geräte haben noch keine Seriennummer verpasst erhalten. Wie willst Du sie an dem identen Eintrag die Geräte unterscheiden ?

Es ist auch ziemlich blauäugig, die Ausgabe von "udevadm info" mit dem Grep Filter zu kastrieren.

Schau einmal mit < sudo devadm info -n /dev/ttyUSB0 > und /dev/ttyUSB1 nach, ob Unterschiede der beiden Geräte bestehen.

ID-Felder, die mit 123456789ABCDEF ö.Ä. ausgefüllt sind, können vom Hostadmin geändert werde. Genauso die Seriennummer, die hier noch auf dem Ausgangszustand der vekauften Geräte "0000:01:00.0" steht.

Wie das genau geht, kann ich Dir nicht sagen, es kam aber hier im Forum bereits einmal vor.

Servus !

DeaD_EyE · Jan 2nd 2023

Vielleicht geht es so:

Code

# Dongle Matchen (Übergeordnetes Subsystem)
KERNEL=="ttyUSB[0-9]*", ATTRS{idVendor}=="0665", ATTRS{idProduct}=="5161", ATTRS{serial}=="A10LSX4A", GOTO="hidraw_a"
KERNEL=="ttyUSB[0-9]*", ATTRS{idVendor}=="0665", ATTRS{idProduct}=="5161", ATTRS{serial}=="0000:01:00.0", GOTO="hidraw_b"
GOTO="end"

# Dongle a
LABEL="hidraw_a"
ACTION=="add", SUBSYSTEM=="hidraw", GROUP="input", SYMLINK+="my_mouse_raw_a"
GOTO="end"

# Dongle b
LABEL="hidraw_b"
ACTION=="add", SUBSYSTEM=="hidraw", GROUP="input", SYMLINK+="my_mouse_raw_b"
GOTO="end"

# Sprungmarke
LABEL="end"

Was sehr eigenartig ist, sind die unterschiedlichen Seriennummern.

Die zweite Seriennummer sieht wie eine Adressierung auf dem Bus aus.

Mach mal ein udevadm info -n /dev/hidrawX -a und dann poste mal von beiden Dongles die Ausgabe.

Wie bei dem Beispiel muss man dann das entsprechend übergeordnete Gerät mit der Seriennummer adressiert werden, um dann zur passenden Sprungmarke zu springen, um dann den Symlink für das Subsystem hidraw anzulegen.

Hi !!

Die ausgabe von udevadm info -n /dev/hidraw0 -a ist:

Code

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Code

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

aus einem anderen Forum wurde mir vorgeschlagen

sudo nano /etc/udev/rules.d/99-usb-serial.rules

Code

SUBSYSTEM=="tty", ATTRS{devpath}=="1.1", SYMLINK+="hidraw0", OWNER="pi"
SUBSYSTEM=="tty", ATTRS{devpath}=="1.2", SYMLINK+="hidraw1", OWNER="pi"
SUBSYSTEM=="tty", ATTRS{devpath}=="1.3", SYMLINK+="hidraw2", OWNER="pi"
SUBSYSTEM=="tty", ATTRS{devpath}=="1.4", SYMLINK+="hidraw3", OWNER="pi"

aber evtl. helfen ja die oberen beiden ausgaben ---

Ausser den Zeilen

< ATTRS{urbnum}=="371732"

> ATTRS{urbnum}=="58290"

zeigt mir "diff" keine verwertbaren Unterschiede der beiden Geräte. Ich weiß aber auch nicht, ob die urbnum aus der Gerätehardware stammt, oder erst anderweitig zugeordnet wird.

Servus !

Googlesuche nach urbnum: Treffer 1. Nicht aus der Gerätehardware. URB für USB Request Block.

Dann wird wohl nur die Änderung der Seriennummer (oÄ) bei einem der beiden Geräte zum Ziel führen.

Servus !

Ich hatte es gestern kurz mit einem RP2040 getestet und bin leider zu keinem Ergebnis gekommen.

Wenn einem die Seriennummer fehlt, könnte man auch über den Pfad gehen, solange die Dongles an den USB-Ports nicht vertauscht werden.

Auch hier hat man das Problem mit den unterschiedlichen Subsystemen.

Das Attribut kommt vom subsytem usb und final wird das Setzen eines Symlinks von hidraw benötigt.

D.h. man muss zuerst die Attribute des subsystems usb adressieren, dann zu einem Label springen, dass dann das subsytem hidraw adressiert.

Einen Generator habe ich bis jetzt leider nicht gefunden. Das wäre ja auch zu einfach. Programm starten, Stick reinstecken, Regel fertig.

Hallo

Wäre das in meinem Fall so richtig ?

44-my-devices.rules

SUBSYSTEM=="tty", ATTRS{devpath}=="1.1", ATTRS{idVendor}=="0665", ATTRS{idProduct}=="5161", SYMLINK+="hidraw0"

SUBSYSTEM=="tty", ATTRS{devpath}=="1.4", ATTRS{idVendor}=="0665", ATTRS{idProduct}=="5161", SYMLINK+="hidraw1"

udevadm info --name=/dev/hidraw0 --attribute-walk

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
