So nice you found a workaround.

It might be related, yes. I'm not familiar with Sigrok codebase but the idea is to check whether this driver runs claim_interface when working on windows (and in fact it should be called on all systems, just some are more forgiving). > Of course we are talking about a clone, and it does work with libusb-win32, > but > with this driver being deprecated I am eager to get it working on WinUSB. > So your thoughts and input are highly appreciated! At this point I hope sigrok developers can chime in. It might be a bug in libusb too but I do not know how to gather enough debug info for the libusb maintainers to fix it. First thing to try would be to make sure claim_interface() is called. And then probably you can use Wireshark to capture all USB traffic in both libusb-win32 and WinUSB cases. That would make for a potentially useful bug report. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com _______________________________________________ sigrok-devel mailing list sigrok-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sigrok-devel
