Con Kolivas 9f74e057 2013-11-09T08:23:23 Use libusb's own zero length packet support unless we have to emulate it on windows since only libusb knows for sure if it's needed.

Con Kolivas b1be5c6d 2013-11-05T19:18:20 Different windows+usb combinations respond with varying levels of reliability wrt timeouts so use a nominal extra 40ms before cancelling transfers that fail to time out on their own.
Con Kolivas 21f18956 2013-11-05T19:11:20 Revert "Use no cancel transfer functions on windows in callback_wait" This reverts commit 8f6acad8ec11fa68e31447e4de9e2ce49c2bf16a.

Con Kolivas ea122100 2013-11-03T20:24:34 Why are we reading extra again in usb read when buffering is enabled? Don't do that.
Con Kolivas 38d9c24e 2013-11-03T20:16:45 Copy known transferred amount back to buffer for usb reads instead of requested length.

Con Kolivas efc605ff 2013-11-03T19:41:56 Ignore iManufacturer from bitfury devices to support bluefury as well as redfury.
Con Kolivas ef0b7d3b 2013-11-03T19:15:32 Add more debugging info for when usb details don't match.

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.
