I believe usb_free_async should check return value of CloseHandle. Otherwise a situation when CloseHandle fails for some reason and not actually closes handle but usb_context_t is being freed nevertheless is entirely possible. This would lead to a resource leak which is nearly impossible to diagnose from a user application.

libusb-win32 project is in a support only mode. Mailing list support is still provided, no changes to the codes and release, unless critical bug found and the fixes are feasible.

@dontech Not sure if this is still relevant or not. Please take a look. We can close it if it is no longer relevant.
