...but always blocks until data is available.
Or so it seem. Now that I've got my weather station code working in Linux I noticed that my timeout value was too short and I keep getting unnecessary many timeouts I noticed that this never happens in Mac OS X, so I think the timeouts don't work on OS X. No matter as I guess no further releases are likely and I don't need them either way anyhow, but thought I'd mention it. My Mac libusb is from macports, don't recall the version number and don't know how to check it. br Kusti ------------------------------------------------------------------------------ Come build with us!

I confirm I can reproduce that on Mac OS X 10.6.1 with libusb 0.1.12. The timeout never happens. I have not yet checked with libusb 1.x + libusb-compat. > No matter as I guess no further releases are likely and > I don't need them either way anyhow, but thought I'd mention it. I also think this "problem" will never be corrected in libusb 0.1.x. Time to move to libusb 1.x?

As soon as it supports Windows, while I'm on Mac and Linux would make most sense for my application I'm afraid 95% of my potential users will be on Windows! cheers Kusti ------------------------------------------------------------------------------ Come build with us!

The idea is that libusb-1.0+libusb-compat-0.1 is compatible with libusb-0.1. > > Time to move to libusb 1.x? > > As soon as it supports Windows, while I'm on Mac and Linux would > make most sense for my application I'm afraid 95% of my potential > users will be on Windows! Does anyone know why the libusb-win32 developers aren't active here? //Peter ------------------------------------------------------------------------------ Come build with us!

Just a hunch, but given the commit rate over at libusb-win32, I don't see any movement this direction from the win32 project's side. The only person who knows AND is willing to post is Xiaofan. Any idea what's going on with Josh Perry? I never did see a link to his repo. Even if it doesn't work yet, it sounds like his modifications took some work and would be interesting to look at...

The only person > who knows AND is willing to post is Xiaofan. I am willing to post in the libusb-win32 because I used it before and it works fine for the applications. But I am not a developer and I do not know too much about the internals of libusb-win32 anyway. If Tim is there, he can probably answer most of the questions as he is a recognized expert in Windows driver development. I think he has already looked into the codes and seen some problems. Example: http://www.nabble.com/Part-of-the-reason-why-libusb-win32-filter-driver-does-not-work-under-Vista-32bit-td23149382.html I agree with you that libusb-win32 does not move basically over the past two years. Maybe Stephan Meyer is really busy with his real work. Even if the libusb-win32 project moves forward with its 1.0 branch, it is not API compatible with libusb 1.0. That is because the libusb-win32 1.0 branch started earlier than libusb 1.0. http://libusb-win32.svn.sourceforge.net/viewvc/libusb-win32/trunk/libusb1/ > Any idea what's going on with Josh Perry?
