Title:
  Usb device not enumerated by xhci, working on older systems

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  My USB2.0 cameras are enumerated fine on ehci systems (older Ubuntus). But not on my new Ubuntu 
  12.10:
  $uname -a
  Linux VAIO 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 
  x86_64 x86_64 GNU/Linux

  here xhci_hcd is compiled in the kernel, and the device is not enumerated. I 
  tried unbinding xhci using the sysfs and the messages dissapear, but ehci does 
  not take over. Any idea?
