Just compiled a 8-STABLE kernel (svn rev 246578).  Initially I get the
almost same errors as above:

  usbus7: port reset timeout
  uhub_reattach_port: port 1 reset failed, error=USB_ERR_TIMEOUT
  uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port 1
  usbd_set_config_index: could not read device status: USB_ERR_STALLED
  usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_STALLED, ignored)
  usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_STALLED, ignored)
  usb_alloc_device: Failure selecting configuration index 0:USB_ERR_STALLED, port 1, addr 3 (ignored)
  ugen7.3: <MagicPixel> at usbus7
  ugen7.3: <MagicPixel> at usbus7 (disconnected)

Could not find documentation but with guessing and trying I got rid of
the first three messages using hw.usb.timings.port_powerup_delay=100:

  usbd_set_config_index: could not read device status: USB_ERR_STALLED
  usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_STALLED, ignored)
  usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_STALLED, ignored)
  usb_alloc_device: Failure selecting configuration index 0:USB_ERR_STALLED, port 2, addr 3 (ignored)
  ugen7.3: <MagicPixel> at usbus7
  ugen7.3: <MagicPixel> at usbus7 (disconnected)

Anything else I should try?

Thanks!
