Re: libusb 1.0.15 beta available

[Nathan H. <hj...@me...>]

Thanks for catching that. Not sure why the missing header doesn't cause an error on 1.8. I will fix it and upload an updated tarball.

I will have to look into the Windows issue. I can't run the code but I can look and see if there is something obvious from the core side.

Any comment on active callbacks vs callbacks via libusb_handle_events? The more I think about it the more I feel active callbacks don't fit the libusb model. I may upload an alternate version that calls callbacks from libusb_handle_events. Either way I will add a simple hotplug example.
