Eltima Software has announced USB Network Gate 4.0 (http://www.eltima.com/products/usb-over-network-mac/) for Mac OS X. The utility Network Gate lets you work with remote USB devices from your local computer over Internet/LAN/WAN as if those devices were plugged directly into your machine.
Version 4.0 adds support for OS X El Capitan. It also includes several stability and interface improvements.
USB Network Gate runs on Mac OS X 10.9 and later and costs $89.95 for sharing one USB device. It’s licensed according to the number of shared USB devices. Every server computer (where the device will be shared) requires a separate license. The client module of USB Network Gate is free and unlimited in quantities used.
