USB dongles are absolutely standard in pro audio. Products made by Steinberg, Avid, and many plug-in shops will not work without a USB dongle.

Aside from a few high-end audio interfaces, most music hardware - including licensing dongles - is USB-A.

Of course you can buy the inevitable wart-on-a-cable adaptor from Apple. But it's both fragile and ugly, and when you have an iLok with thousands of dollars of software on it, you really don't want fragile.

Edit: to be fair, some of these licensing schemes are moving to cloud licensing. But that has issues of its own - and not all are.
