PFA , I have attached dmesg log and /proc/interrupts before and after
recording through the headphone.
Your dmesgafter.txt file is identical to the dmesgbefore.txt file.
Weren't there any new kernel messages while the test was running?
There should have been some messages when the headphone was plugged in.
Both dmesg was taken after plugging the headphone, but one is taken
before recording and the other after recording.
The lines which showed hardware bug according to you were still in that
dmesg log.
I have also attached the usb_mon log.
You sent two copies of the same usbmon log: 1.mon.out is identical to
usbmon.txt. They show that recording from the headphone worked. They
also show that the mouse and keyboard worked while the recording was
taking place.
But the usbmon log doesn't show anything after the recording ended. So
I really need to see the dmesg log for after the test. I also need to
see the "periodic" and "registers" files for after the test.
The material you sent doesn't show any reason for the mouse and
keyboard to stop working.
If you have any other USB ports, you could try plugging the keyboard or
mouse directly into the PS3 instead of into the hub.
There's another thing you can try: Force the hub to use the OHCI
controller instead of EHCI. To do that, type
echo -n sb_05 >/sys/bus/usb/devices/usb3/../driver/unbind
and of course, don't rmmod ohci-hcd.
Initially the recording from headphone works ,but when I try to stop
using ctrl+c , it goes on printing "^c" character ,then prompt keeps
coming continuosly.
Finally, not able to use my keyboard and mouse. If I rmmod EHCI things
work fine , but I want to use camera ,which uses higher bandwidth.
Whatever log I have sent you is by remotely logging and copying the
files from the PS3 system.
If possible please find your time of convenience wherein we will try to
find the problem in single day.
Try Thursday starting around 10:30 AM my time (UTC-0400).
Suddenly , my LAN is not working properly, so it may be difficult to
provide you relevant data .
I will try my best to make it work tomorrow.
