Con Kolivas 691a681f 2013-10-26T20:24:51 Remove inappropriate extra locking in _usb_transfer_read
Con Kolivas 0657b64e 2013-10-25T13:36:21 Only set libusb cancellable status if the transfer succeeds.
Con Kolivas 0da551fa 2013-10-25T12:30:39 Use a linked list for all usb transfers instead of just cancellable ones.
Con Kolivas 7b5884ca 2013-10-25T08:43:55 Add cancellable transfers correctly to the ct_list

Con Kolivas 51660838 2013-10-24T21:58:25 Don't bother having a separate cancellable transfer struct for usb transfers, simply include the list in the usb_transfer struct.
Con Kolivas c96f0965 2013-10-24T21:54:35 Add wrappers for usb_read_cancellable and usb_read_timeout_cancellable
Con Kolivas c2c69877 2013-10-24T21:52:50 Specifically set the cancellable state for it to not be uninitialised in the usb transfer struct.

Con Kolivas 1d9f90b2 2013-10-14T11:39:15 Revert "Convert the usb callback function to use a cgsem_t using the timedwait code to avoid races with mutexes/conditionals." This reverts commit 433465bcfcd8d9a2270cb27dd0ea933e9fefa829. Not ready yet.
Con Kolivas 433465bc 2013-10-14T11:35:47 Convert the usb callback function to use a cgsem_t using the timedwait code to avoid races with mutexes/conditionals.
Con Kolivas 9ca22ed4 2013-10-14T10:05:49 Use the one LIBUSB_ERROR_TIMEOUT for cancelled transactions since this error is explicitly tested for in various drivers.

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 6d18ce4c 2013-10-11T14:37:40 Retry up to USB_RETRY_MAX times to clear a halt condition before failing.
Con Kolivas 3a7a677f 2013-10-11T13:43:16 Show the error number as well as the description in erroring bulk transfers.
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.
