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.

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.

Try Thursday starting around 10:30 AM my time (UTC-0400).
