Con Kolivas bec75b61 2013-10-16T20:34:51 Make the USB polling thread poll every second to potentially aid longer timeout transfers.
ckolivas f821d0fb 2013-10-15T13:31:07 Set device_diff on work in get_work to not be missed with drivers that use get_work directly.
Con Kolivas 9e287f95 2013-10-14T03:27:57 Merge pull request #499 from someone42/master changes to bitburner driver for bitburner fury boards
Con Kolivas 07837072 2013-10-14T12:12:01 hexstr is too small in test_work_current

Con Kolivas 9f8023a9 2013-10-12T10:34:07 Use stack memory for hex used in stratum share submissions.
Con Kolivas e0c90359 2013-10-12T09:56:48 Use stack memory in test_work_current, avoiding a malloc/free cycle each time.

Con Kolivas 58008a37 2013-10-12T09:05:58 Add a hash_driver_work function to allow for drivers that wish to do their own work queueing and management.
Chris Chua b509e843 2013-10-03T20:11:37 using separate identifier for bitburner fury boards
Con Kolivas cda797d1 2013-10-11T16:04:23 Avoid calling get_statline_before on exit to avoid trying to use it on drivers in an indeterminate state.
Con Kolivas d437de84 2013-10-11T15:58:29 Avoid calling get_statline on exit.
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.
Con Kolivas 853aa28f 2013-10-11T08:49:59 Merge branch 'master' into async Conflicts: usbutils.c
Con Kolivas 2834eb8d 2013-10-08T23:35:22 Kill off threads that have failed using hash_sole_work instead of just disabling them.

Con Kolivas 8c0ea19e 2013-10-05T09:31:36 Submitting an ntime offset nonce needs to be done on a copy of the work instead of the original so abstract out shared components as much as possible, minimising strdups in copy_work and make submit_work_async work take copied work, cleaning up code in the process.
