[Libusb-win32-devel] libusb-win32 and OpenUsb

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

Is it possible that libusb-win32 1.0 to follow the API of OpenUSB?
http://openusb.sourceforge.net/

OpenUSB currently only works under Solaris and Linux. But they
would like to extend the support to Mac OS X, Win32 and BSDs.

Regards,
Xiaofan

I failed to see the advantage of using OpenUSB. Can you please elaborate
why one should want this?

OpenUSB is supposed to be based on the libusb 1.0 API and has the
aim to be thread safe and support isochronous transfer (libusb-win32
already support iso transfer). It also has a compatibility layer so
that libusb-0.1 based program will still run.

I am not too much into the technical details of OpenUSB. I just
think it would be nice for libusb-win32 to be in-sync to l with
OpenUSB which is a fork of libusb 1.0 (libusb 1.0 is kind of dormant
now).

One more thing, OpenUSB is backed by SUN, a corporration. This
can be a good (or not so good) depending on your interpretation.
For me I think so far it is positive. OpenUSB is still in the development
stage but the API, the frontend and Solaris/Linux backend are almost
finished.

To make OpenUSB cross-platform, Win32 is important. So I think if
SUN really persists, they will come out a Win32 port. Then it
might not be a good idea to have two incompatible API for
Windows.

Oh... It seems I totally missed that OpenUSB wants to REPLACE libusb. I
had the impression that it is just another layer on top of libusb.

The only positive aspect I can think of: SUN might want to afford the
$$$ needed to sign the Windows driver. ;)

The Windows API is there, they are free to use that. (just kidding)
