Here is a patch which might help. Send another copy of the "periodic" file with the patch installed, so I can see whether it is working properly.
PFA periodic file after applying the patch The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee s and may contain proprietary, confidential or privileged information. The output makes it clear that there won't be enough allocatable bandwidth to send data out to the headphone, but there should be enough to read data in. Try reading some data, and after it fails, send the output from dmesg together with the usbmon log.

It looks like your hardware is really buggy. Here's an additional patch to get some more information. Let's see what shows up in the dmesg log with this. Alan Stern Index: usb Please clarify the kind of hardware problem my system has. It's Sony's PS3 system. You forgot to attach the log file. I don't know; I have never used a PS3. If we're lucky, the log will indicate the reason for this problem. This time I have attached it. You didn't use the headphone! The log file doesn't show any errors.
Then run the same test again, this time reading data from the headphone. I am attaching the dmesg log with this mail. The bus numbers may change from one boot to another, so "usb4" might not be the right number. Okay, run usbmon also. Don't start it until after those echo commands. One more thing. Then after the mouse and keyboard die, make another copy of the same file. Attach both copies along with the dmesg and usbmon logs.
If possible please find your time of convenience wherein we will try to find the problem in single day. Thanks a lot. Your dmesgafter. 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. 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. The lines which showed hardware bug according to you were still in that dmesg log. Finally, not able to use my keyboard and mouse.
Whatever log I have sent you is by remotely logging and copying the files from the PS3 system. I will try my best to make it work tomorrow. When the headphone was plugged in, there should have been a line like this: usb You mean these lines? They are unrelated to EHCI and the headphone.
What happens if you stop the recording by using "kill" over the network connection? I understand. This is a very difficult problem to investigate. Can you try plugging the hub, together with the mouse, keyboard, and headphone, into a regular PC running Linux? If it works, it will indicate that the software is probably okay and something is wrong with the PS3 hardware. Do I need to enable any kernel configuration for that. Same kernel in x86 machine works fine with these devices.
But I dont know whether they are directly connected or through hub. When I reboot my system on the screen I get some usb error messages saying "cable may be bad". Is this the reason for my problem. Please tell me if any further analysis is required to investigate the problem and if it's a hardware problem how to investigate that. It should have appeared just like the lines for "usb Were you able to get this yet?
It affects the way ohci-hcd manages its root hubs. I mean to take the hub that those devices are plugged into and move the hub, along with the devices. Or is the hub built into the PS3? How do you expect me to tell from just four words? You have to provide a lot more information than that. Here's something else you can try. After you stop the headphone recording and before you stop the usbmon process or collect the dmesg log , unplug the hub and immediately plug it back in.
Do the keyboard and mouse work then? One other thing. It's possible that the problem is in the GL hub; I have heard reports about problems with Genesys Logic's hubs before.
