That's the only dongle I've seen so far that runs ADuM5000, ensuring a full galvanic isolation between the device and the host.
There are two independent isolators which works individually for USB. One of them is USB digital signal isolation device, ADUM4160 of Analog Devices, which purify signal of DDC. The other is USB power isolation device, ADUM5000 of Analog Devices. ADUM5000 works to isolate input power and purify it again to supply.
