Have you tried an add-on PCI USB-2 card? (The lsusb output suggests you don't.) That's the combination most likely to work. If you can do that, attach the corresponding usbmon trace.
If you don't have any USB-2 ports on the PCI card, attach a usbmon trace using a USB-2 port on the motherboard. -- 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
