Steve Conklin, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** This bug is no longer a duplicate of bug 795626 [Asus A8V-E DELUXE] ehci_hcd fatal error - USB devices randomly crash ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/954704 Title: USB device disconnect leads to all devices on hub disconnecting Status in “linux” package in Ubuntu: Incomplete Bug description: Steps to reproduce: 1. Connect a pl2303 USB to serial adapter to the system 2. Connect a device that generates some serial data periodically 3. Open minicom and view data from device 4. Close minicom but leave device connected to the serial adapter (some time passes) 5. At some point, when the device sends data, the serial USB device disconnects, and takes down all devices on the internal hub. Here's what's in dmesg: [42835.631467] usb 1-1.6: USB disconnect, device number 8 [42835.631634] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [42835.631646] pl2303 1-1.6:1.0: device disconnected [42835.866365] usb 1-1.6: new full speed USB device number 9 using ehci_hcd [42835.958021] ehci_hcd 0000:00:1a.0: fatal error [42835.961893] ehci_hcd 0000:00:1a.0: HC died; cleaning up [42835.964703] ehci_hcd 0000:00:1a.0: force halt; handshake f8426024 00004000 00004000 -> -110 [42835.964706] ehci_hcd 0000:00:1a.0: HC died; cleaning up [42835.973864] usb 1-1.6: device descriptor read/all, error -108 [42835.973870] hub 1-1:1.0: cannot disable port 6 (err = -19) [42835.973879] hub 1-1:1.0: cannot reset port 6 (err = -19) [42835.973882] hub 1-1:1.0: cannot disable port 6 (err = -19) [42835.973887] hub 1-1:1.0: cannot reset port 6 (err = -19) [42835.973889] hub 1-1:1.0: cannot disable port 6 (err = -19) [42835.973894] hub 1-1:1.0: cannot reset port 6 (err = -19) [42835.973897] hub 1-1:1.0: cannot disable port 6 (err = -19) [42835.973900] hub 1-1:1.0: unable to enumerate USB device on port 6 [42835.973902] hub 1-1:1.0: cannot disable port 6 (err = -19) [42835.973907] usb 1-1.1: USB disconnect, device number 3 [42835.974005] ftdi_sio ttyUSB1: FTDI USB Serial Device converter now disconnected from ttyUSB1 [42835.974012] ftdi_sio 1-1.1:1.0: device disconnected [42835.974059] usb 1-1.2: USB disconnect, device number 4 [42836.065807] usb 1-1.3: USB disconnect, device number 5 [42836.161569] usb 1-1.4: USB disconnect, device number 6 [42836.225349] usb 1-1.5: USB disconnect, device number 7 [42836.392778] usb 1-1: USB disconnect, device number 2 == end of what's in dmesg == ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: linux-image-3.0.0-16-generic-pae 3.0.0-16.29 ProcVersionSignature: Ubuntu 3.0.0-16.29-generic-pae 3.0.20 Uname: Linux 3.0.0-16-generic-pae i686 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
