usbredir for Mac

usbredir is a low-level library for USB traffic redirection, primarily addressing the problem of forwarding local USB devices over a network for use by remote systems. It is commonly invoked in virtualization and remote desktop scenarios, allowing virtual machines or remote hosts to access peripherals such as USB flash drives, dongles, and serial converters as if a real device were plugged in. Ordinary users typically do not run it directly; instead, it is called in the background by remote connection solutions such as SPICE. It suits developers and operations personnel who need to share USB devices across machines, as well as technical teams building virtualized desktop environments. On the command line it can be used with related tools for debugging and forwarding, making it a rather infrastructure-oriented component.
