9ca22ed493 Use the one LIBUSB_ERROR_TIMEOUT for cancelled transactions since this error is explicitly tested for in various drivers. 2013-10-14 10:05:49 +11:00

84f642f563 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. 2013-10-12 15:06:48 +11:00

03ad59f287 Add a small amount to the usb timeout before cancelling to allow for a regular usb polling interval to pass. 2013-10-11 15:37:55 +11:00
Con Kolivas
08d8612f68 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. 2013-10-11 14:47:01 +11:00

b5dfacef24 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. 2013-10-11 10:15:06 +11:00
