[Bug 332643] Re: usb hub disappears after one use
Thanks for posting back. I'll close this bug, I think it was probably a hardware issue (like loose wires). If the problem re-appears, please re-open the bug by changing the status back to New. ** Changed in: linux (Ubuntu) Status: Triaged = Invalid -- usb hub disappears after one use https://bugs.launchpad.net/bugs/332643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 332643] Re: usb hub disappears after one use
I never got a chance to try with Jaunty. However, at some point this misbehavior seemed to disappear. I'm not sure if it was after a kernel upgrade or if some wires got jiggled or what. Whatever happened, the hub is now working correctly as it should. The system is now running linux-image-2.6.24-24-generic version 2.6.24-24.56 (though as I said, I didn't notice exactly when this stopped being a problem - for a long time I've just been assuming it is still broken and applying the workaround unconditionally). I'd be content to see this closed as fixed now. If the problem resurfaces in the future, I can re-open it or file a new ticket. -- usb hub disappears after one use https://bugs.launchpad.net/bugs/332643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry for the delay in getting back to you. I can't seem to see the source of the problem myself, but we'll mark the bug as Triaged so a developer can have a look at it. Hopefully they will be able to track the source of the problem.

[Bug 332643] Re: usb hub disappears after one use
Attaching a log including several full cycles of plugging in, removing, and plugging back in. Surprisingly, for the first time since I started having this difficulty, I was able to go through the cycle more than one before the failure occurred. The attached log represents these events: 20084 - plugged the monitor's USB cable in to a USB port on the motherboard. A usb mass storage device was plugged into the monitor at the time. 20426 - unplugged the usb mass storage device 20430 - plugged the usb mass storage device back in 20439 - unplugged the usb mass storage device (apparently a little too soon, as some usb mass storage specific errors follow this event in the log file) 20444 - plugged the device back in 20484 - unplugged the device A few seconds after unplugging the device at 20484 I plugged it in again, but no new lines appeared in dmesg output for that event. Several further plug/unplug cycles also added no further lines. ** Attachment added: plug-unplug-cycle.txt http://launchpadlibrarian.net/23014781/plug-unplug-cycle.txt -- usb hub disappears after one use https://bugs.launchpad.net/bugs/332643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 332643] Re: usb hub disappears after one use
That is strange. Can you please also upload as separate attachments sudo dmidecode dmidecode.txt Unplug the device and rmmod/modprobe the appropriate modules until the cycle should work again, and run lshal lshal_1.txt while the device not the monitor) is unplugged. Now open a separate terminal and run lshal -m leave this running... Then do your device plug in and unplug cycles until it doesn't work anymore and run in the original (or new) terminal, run lshal lshal_2.txt while the device (not the monitor) is unplugged. Please upload the lshal_1 and _2 files and copy and paste the lshal -m output here as well.

[Bug 332643] Re: usb hub disappears after one use
Okay, attaching several files. dmidecode.txt generated as you requested. lshal_1.txt is the output of lshal after removing all usb- related modules and then reloading them while the usb device was not plugged into the monitor. However, this seems to have left the system in a state where it couldn't recognize the usb device even once. lshal_2.txt is the output of lshal after removing all usb-related modules and then reloading them while the usb device *was* plugged into the monitor. This caused the system to notice the usb device right away. The first time I unplugged the usb device and tried plugging it back in, it wasn't recognized. lshal_3.txt is the output of lshal after that. lshal_m.txt is the output of running lshal -m while all that was going on. -- usb hub disappears after one use https://bugs.launchpad.net/bugs/332643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

By the way, I haven't had a chance to test with a Jaunty LiveCD yet (some cables need to be fiddled around with first), but I will try to do that at my earliest convenience.

Re: [Bug 332643] Re: usb hub disappears after one use
Thanks for attaching those, I'm attaching the diffs for convenience. It sounds to me like the USB hub may not be receiving enough power and is getting disabled because of it. When you ran the USB cable to the monitor's USB hub, is the other end plugged into a separate USB hub that is its own external device (i.e. not built into the motherboard or not a PCI card)? Have you tried plugging that cable into different USB ports on the computer? Is the device you are plugging in self powered or is it drawing all its power from the USB cable? It looks like a storage device, so would it be a flash drive, 2.5 external, or 3.5 external, or something else like an ipod?

[Bug 332643] Re: usb hub disappears after one use
The monitor is plugged directly into a port on the motherboard. All the available USB ports (at least the ones which are connected) are on the back of the motherboard in the same area. I've done very superficial testing with most or maybe all of them (with roughly the same results), but I'll do a more thorough check later on and report the results. The USB device is a flash drive - in particular, one of these: http://www.daydeal.com/product.php?productid=20388cat=1014 -- usb hub disappears after one use https://bugs.launchpad.net/bugs/332643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for reporting this. Can you please attach a dmesg that includes a full cycle of plugging in a device, removing it, then plugging the device back in without reloading modules? If possible, can you please also try to reproduce this on a Jaunty (development) LiveCD? You can find out more about the development release at http://www.ubuntu.com/testing/ .
