[yavdr 0.5 beta] graphlcd operation not permitted - gelöst

andi82 · 6. Oktober 2012

Ich bekomme mein Alphacool Display unter 0.5 beta einfach nicht zum laufen.
Folgendes taucht in den Logs auf:

Code

vdr vdr: SDCONNusb_claim_interfaces(): usb_claim_interface() unsuccessful for interface 0. rc=-1, error: Operation not permitted

Bei vorherigen Versionen musste man die udev rules anpassen und das Rechteproblem hat sich erledigt (siehe auch alte Threads dazu).
Egal was ich aber auch für eine Regel setze es funktioniert nur als root. Habt ihr eine Idee? Meine momentane udev Regel:

Code

SUBSYSTEM=="usb", ATTRS{idProduct}=="060c", ATTRS{idVendor}=="04eb", GROUP="vdr", MODE="0666"

Hat die udev-Regel denn den gewünschten Effekt auf die Rechte des Geräts?

hm, ich nehme an du meinst sowas wie /dev/ttyUSB0? Das gibts gar nicht, wie finde ich denn raus welches Gerät es ist?

seahawk1986 · 6. Oktober 2012

Das wäre doch mal der erste Schritt das herauszufinden... z.B. mal die dmesg-Ausgabe nach Produkt- und Vendor-ID durchsuchen und schauen was da für das Gerät angelegt wurde.

in dmesg tauch das Gerät erstmal nicht auf. Wenn ich es jedoch aus und wieder einstecke habe ich folgendes im Log:

Code

Oct  6 16:27:15 vdr kernel: [ 3683.988590] usb 2-1.1: new full-speed USB device number 17 using ehci_hcd

Mach doch mal

---
udevadm test /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1

Sehr gut, danke!
Jetzt habe ich das Gerät /dev/bus/usb/002/018
Wenn ich darauf ein chmod mache funktioniert das Display. Wie schreibe ich nun eine passende udev Regel?

Keine_Ahnung · 6. Oktober 2012

udevadm test gibt dir auch aus wer welche Rechte setzt. Poste mal die Ausgabe davon.

Deine Regel greift gar nicht.

Und der Name sollte mit 40 Anfangen und nicht mit 040. Aber das ist nicht das Problem.

Du hast in der UDEV Regel Produkt und Vendor vertauscht. Deswegen wird sie gar nicht angewendet.

Ferner sollte dein VDR der Gruppe uucp angehören (zum testen "id vdr") wenn du das graphlcd Plugin instalierst, daher sollte die UDEV Regel sollte "GROUP="uucp", MODE="0660"" setzen, das ist so genormt

Vielen Dank, es funktioniert nun mit folgender udev rule:

Code

SUBSYSTEM=="usb", ATTRS{idProduct}=="04eb", ATTRS{idVendor}=="060c", GROUP="uucp", MODE="0660"
