Con Kolivas c0690286 2013-10-12T17:44:28 Free a libusb transfer after we have finished using it to avoid a dereference in usb_control_transfer
Con Kolivas 84f642f5 2013-10-12T15:06:48 Although async transfers are meant to use heap memory, we never return before the transfer function has completed so stack memory will suffice for control transfers, fixing a memory leak in the process.

Con Kolivas 03ad59f2 2013-10-11T15:37:55 Add a small amount to the usb timeout before cancelling to allow for a regular usb polling interval to pass.
Con Kolivas 08d8612f 2013-10-11T14:47:01 Do not attempt to clear a usb halt before sending the cancel message since all transfers should normally be cancelled before attempting to clear a halt condition, and only change the return message to a timeout if it's consistent with a cancellation.

Con Kolivas b5dfacef 2013-10-11T10:15:06 We are always dependent on libusb handling events so use the blocking libusb_handle_events in the polling thread and use a bool to know if we should continue polling.
