how to solve it, I had a similar problem, thanks

thanks for your reply , best wishes @TomHVR

This problem exists in windows, when using asynchronous interfaces to send data, when close the device, it is very serious that the system must be restarted, otherwise the program cannot...


There seems to be a deadlock, causing the program to freeze

I added printing to core.c and confirmed that the program was stuck at usbi_backend.close(dev_handle) ， using version: V1.0.26.11813.   @tormodvolden
