DVD disk recognized only after reboot - filippobistaffa - 2016-10-18 I am running LibreELEC build v17 (Milhouse build #1016) on a Raspberry Pi 2, with an external USB DVD drive. The drive has an auxiliary USB power supply, hence I assume it is adequately powered. If I insert a DVD while the system is running, it seems it is not correctly recognized. Running dmesg, I see that the following errors appear: Code: [ 104.118530] sr 0:0:0:0: [sr0] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 Even if DVD autoplay is activated, nothing happens, and I cannot play the DVD even if I manually try to start it. This happens both with commercial and non-commercial DVDs, hence I think the problem is not related to CSS-related stuff. On the other hand, if I reboot the system leaving the DVD inserted, everything works OK: I get no dmesg errors and I can play every DVD correctly? Any idea how can avoid rebooting every time?

The drive has an auxiliary USB power supply, hence I assume it is adequately powered. I've had this happen, and it boiled down to a power supply problem. When you say 'auxiliary USB power supply', where do you draw the power from? - some of my drives have a separate 5V power supply plugged into the mains, and I think that relying on an additional USB socket for supply might not give you enough.

An external power supply for a drive may just provide, e.g. 12V for the motor. The 5V power may still be drawn from the Pi's USB connection (and that may be a significant amount). Is the power supply to drive, 5V or something else? RE: DVD disk recognized only after reboot - filippobistaffa - 2016-11-20 Here's how the DVD drive (on the left) is connected: The charger on the right is this one. If it's a power issue, how come it's not happening if the disk is in from the boot? @taiebot how can I install udisks in order to try the workaround? |
