Con Kolivas 4c0b6438 2013-11-02T12:29:08 Instead of using complicated sleeps to emulate characters per second on usb writes, submit only as many characters as can be transferred per usb poll of 1ms, and use timeouts in bulk transfers, cancelling transfers only as a failsafe.

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.
