Okay, then I guess there's nothing more I can do regarding Bug #13304. Can you take it over? Yes, as I mentioned, it is on my to-do list. I'll bump up the priority now that there are two users reporting the problem. -Geoff ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

I still don't see any lines about the headphone device in the log. Was the headphone plugged in during boot, or did you plug it in later? Then , periodic and registers files and also the usbmon log. Here's what your registers file says: bus ps3_system_bus, device sb_05 (driver 10 Dec 2004) PS3 EHCI Host Controller EHCI ff.ff, hcd state 1 structural params 0x capability params 0x status Async Periodic Recl Halt IAA FATAL FLR PCD ERR INT command park=3 ithresh=63 LReset IAAD Async Periodic period=??

It indicates that the CPU was unable to communicate with the EHCI controller at all! All the memory-mapped I/O reads returned 0x. No wonder the keyboard and mouse stopped working. I have no idea what could have caused this to happen. Even if the controller had suffered a fatal error, you wouldn't see this. It looks like the bus's connection to the controller was turned off. I'm CC-ing the PS3 maintainer and mailing list. Maybe people there can help. I am even not able to kill the application because it's not showing when I use top command. I addition to that I get some messages during boot up . they are Unable to accept address for port 1 (error -62) usb cable may be bad Unable to accept address for port 2 (error -62) Those are normal. They occur because your system loads ohci-hcd before ehci-hcd. It should load ehci-hcd first.

I'm CC-ing the PS3 maintainer and mailing list. Maybe people there can help. Alan Stern There is a known but yet unfixed bug for the PS3's EHCI Async Periodic (typically audio recording) device handling. There are a few related hardware errata that I have not yet implemented driver fixes for that I think are causing it. I guess it is the same problem as reported by Abhishek since Andrew's dmesg (http://www.osl.iu.edu/~afriedle/dmesg.txt) shows similar results. More info is here: http://ozlabs.org/pipermail/cbe-oss-dev/2009-February/006365.html I have bought a ART Tube USB device but have not had time to fix this bug. It is on my todo list. Please feel free to make an attempt. Alan, thanks for your effort on this so far, sorry you didn't know about the previous report. -Geoff ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
