[Libusb-devel] hidapi feature extension and pywinusb for HID device

[Xiaofan C. <xia...@gm...>]

Now it seems that there are some interests in the HIDAPI since it
offers a true cross-platform API for the HID device (at least under
Linux, Windows and Mac OS X, probably can be extended to
FreeBSD 8/9 with the compatible libusb10 API).

Looking at the hidapi.h, it seems to me hidapi is quite simple
right now. So it might be a good idea to get some extension
to it.

For example, right now libusb-1.0's HID API does not
deal with HID Collections. HIDAPI does not seem to support
that either. Under Windows HID API, you may have to deal with
HID Collections.

Indeed, one commercial usbhidapi library provide the feature.

The other missing feature is hot plug support. Actually
the open source Python based pywinusb project
has some support of hotplug (for HID device under Windows).
pywinusb seems to be quite nice under Windows.
