Con Kolivas 74f3f9d6 2013-11-09T08:00:36 Sleep in avalon send task on return to the function to allow other code to work during the sleep period.
Con Kolivas c3f13369 2013-11-08T18:15:08 Do the driver flush in avalon code lockless since it can lead to deadlocks.
Con Kolivas 176747fb 2013-11-07T23:22:11 Check for fatal read errors and break out of the read loop in avalon.
Con Kolivas 79196e6a 2013-11-07T22:34:05 Send errors are basically fatal in avalon driver so break out of the send tasks loop.
Con Kolivas 79022974 2013-11-07T22:29:33 Make the avalon driver return -1 for hash count when usb fails, allowing the main loop code to send it the shutdown flag.
Con Kolivas 2dd7d2f6 2013-11-07T22:11:08 Use usbutils' own ftdi parser for avalon and the ftdir's own latency for managing timeouts since we can wait on reads with completely asynchronous reads+writes.

Con Kolivas 8fb7a0d1 2013-11-04T08:45:09 Always use a usb read buffer instead of having to explicitly enable it.
Con Kolivas fc80e2fe 2013-11-03T20:31:04 Deprecate preferred packet size functions in usbutils since they're unhelpful.

This reverts commit 7be59992c121a61e56402cec21508e39401fad6c. Of dubious utility since a full nonce range is not scanned before loading more work.
