Passing product_id=0 will match any product of a given vendor. This patch
makes it also possible to use vendor_id=0 to match any vendor for a given
product id.
Windows code added to Ludovic's patch by Alan Ott.
Improve logic of report length field handling for empty fields.
Add column headers for data and length fields.
Add documentation statement about length fields.
Increase window size.
Add message boxes when invalid values are entered.
memset() buffers to zero.
Using locations makes the path the same for each run of a HIDAPI based
program. This is useful for opening devices which don't have a serial
number, and where multiple devices of the same type are attached to the
system at once.
This references pull request #78.
There were errors regarding the length of strings in conversion from CFString
to wchar_t.
Thanks to github user nikolajsheller for pointing this out in pull request #80.
Use kIOHIDOptionsTypeSeizeDevice instead of kIOHIDOptionsTypeNone to
avoid interferences with other applications trying to use the HID device
at the same time.

Remove device_list, which was used to match up IOHIDDeviceRef's and
hid_device's in the device removal callback. This was needed because the
removal callback was attached to the whole IOHIDManager, instead of
individual IOHIDDevices.
Instead attach the removal callback to each IOHIDDevice individually,
and have a pointer to the device's hid_device passed to the callback.
Windows will enumerate a device before the driver has been attached to
that device. This is problematic, and causes hangups on Windows 7
(possibly othes) when the device is opened before a driver is attached
and then closed. This patch makes sure that a driver has been attached
to the device before putting it in the enumeration list.
This adds the familiar autotools build system and associated documentation
for Linux, FreeBSD, Mac, MinGW, and Cygwin. The old Makefiles have been
kept, and where appropriate have been renamed Makefile-manual.

Addresses an issue with the return type of HidP_GetCaps() which was
returning the wrong status code because of the invalid return type of
BOOLEAN which is a UCHAR. The return code is supposed to be 0x110000
which obviously doesn't fit in a UCHAR so it was being rounded to
0x0. Basically, no return codes were ever making it through that call.
