Tim: This has nothing to do with USB-3. You can tell from the log: > Dec 6 13:33:29 twpsamlinux kernel: [ 512.148960] usb 3-1: new full- speed USB device number 2 using ohci-pci
OHCI is strictly USB-1.1. However, you have not provided nearly enough useful information to tell what's going wrong. You didn't even say what version of the kernel you are using! -- let alone provide a usbmon trace like some of the other people contributing to this bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1136110 Title: USB Audio Codec choppy playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
