Version-Release number of selected component (if applicable): kernel-2.6.12-1.1381_FC3smp How reproducible: Always Steps to Reproduce: 1. Plug in SpeedTouch 330 USB modem. 2. Unplug modem after a while. 3. Check logs. Actual Results: The following trace is left in dmesg: usb 4-2: USB disconnect, address 6 usb_unlink_urb() is deprecated for synchronous unlinks. Use usb_kill_urb() instead.

Additional info:
The right fix would be to replace usb_unlink_usb with usb_kill_usb in speedtch, though it's probably more polite to add a stub into FC3 kernel. I suspect this happened because we moved on a new upstream kernel.
