Hello, I'm experiencing this problem too since the newest kernel upgrade from 2.6.31-14 to 2.6.31-15 on Karmic Koala. I'm attaching my lspci -vvv. I've experienced the problem with older kernel versions but it seemed to be gone up until now.
Thanks, Alex ** Attachment added: "lspci -vvvv" http://launchpadlibrarian.net/36110203/lcpci.txt -- USB ports: connect-debounce failed, port disabled https://bugs.launchpad.net/bugs/88530 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
