The usbredir_handle_msg receive message and do usbredirhost_read_guest_data(),
but does't make libusb call work. And after default 60 secs timeout in 
libusb_handle_event(), usbredir_write_flush_callback() and 
usbredir_write_callback() work while no message are received through
usbredir_handle_msg(). Where should I check?

On window 7 and libusb 1.0.10
