Cubietruck 4 USB erkennt keine cdrom

Wernieman · 15 Juli 2015, 08:44:58

Irgendwas ist komisch .. gehen wir mal anders ran:

udevadm monitor

Und dann das Laufwerk reinstecken ...

Hi,

bin erst heute Abend am rechner vor Ort, OK?

Hi,

hier die Infos!

udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

Hi Wernieman,

können wir irgen wie anders kommuizieren?

Wernieman · 15 Juli 2015, 20:07:04

Bin nur nicht immer am Rechner ;o)

mal prinzipiell ... ist der Rechner übers Netz (ssh) erreichbar?

Es ist mir eigentlich ein Rätsel .. irgendwie ist Dein System komisch. Kannst Du bitte mal das gleiche mit einem USB-Stick posten?

Bei mir erscheint (bei einem USB-Stick) und damit sdf:

Du siehst, er registriert den Stick als sdb (und die Partition als sdb1)

Komischerweise macht er es NICHT bei Deinem CDROM (DVD) ... muß mal hier in einer Grappelkiste gucken ...

Dir fehlt irgendetwas im Kernel ... bevor ich jetzt da weitersuche (habe hier keinen Cubi), könntest Du mal probieren, Dich an ein Cubi-Forum zu wenden? Ist kein FHEM, sondern ein Cubi/Linux-Problem

(

Und eines, was ich mir nicht vorstellen (und nachbauen) kann

(

P.S. in der /var/log/syslog oder /var/log/kern.log steht auch nichts auffälliges?

Poste mal die letzten zeilen der kern.log nach Einstecken Deines DVD-Laufwerkes ...

Weisst Du, in meiner Verzweiflung, habe so einige Foren angeschrieben, auch Cubietruck Forum, sogar auf Englisch.

Keine Hilfe oder Antworten.

Tja, so ist das halt.

1. Kleiner Tip: Nutze die "code" Tags, macht es lesbarer ...

2. mich stören folgende Zeilen:

Code Auswählen

Jul 15 20:11:40 cubieboard4 mtp-probe: checking bus 1, device 7: "/sys/devices/platform/sunxi-ehci.1/usb1/1-1/1-1.2"
Jul 15 20:11:40 cubieboard4 mtp-probe: bus: 1, device: 7 was not an MTP device

Kannst Du es mal mit minimierter USB-Belegung Testen?

geromme · 15 Juli 2015, 20:45:58

verstehe das mit den tags nicht?
und meinst du ich soll nur den dvd player dran hängen und die anderen usb leer lassen?
