[Kernel-packages] [Bug 1371233] Re: USB 3.0 connection is unreliable + xHCI xhci_drop_endpoint called with disabled ep
I was affected by usb3.0 for years. Once Kernel 3.12(test release, linux- headers-3.12.0-031200rc2-generic_3.12.0-031200rc2.201309231935_amd64.deb, etc) has resolved my issue and works for a year, but since I update ubuntu to 15.04, it appears again and again. I have the phenomenon as link described, http://unix.stackexchange.com/questions/91027/how-to-disable-usb-autosuspend-on-kernel-3-7-10-or-above. I'm testing #44 suggestion, and I hope it will help me to step out the issue. Thanks, Malachi de AElfweald (malachid) I will give back the test result tomorrow. -- 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/1371233 Title: USB 3.0 connection is unreliable + xHCI xhci_drop_endpoint called with disabled ep Status in linux package in Ubuntu: Incomplete Status in linux source package in Trusty: Incomplete Status in linux source package in Utopic: Incomplete Status in linux source package in Vivid: Incomplete Bug description: based on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358871/comments/7 I tested with the HDD enclosure IcyBox IB-351 series with USB 3.0 connection with the same result (connection drops after 300 MB reading, error message "xHCI xhci_drop_endpoint called with disabled ep" occurs sometimes, other devices (e.g. Samsung HD103SI 1 TB HDD connected with 3.0 USB adapter to eSATA of enclosure) read hundreds of GB before failing, but definitely do before reading 1TB).
