If there are no USB 3.x port then you can use a TB2 to USB 3.x adapter to gain those ports, these adapters will have USB-A ports and not USB-C ports. If your MacBook Pro has USB 3.x ports then use them to connect a USB 3.x hub or dock. USB 3.x docks and hubs with USB-C ports exist, but are rare in my experience, and will not work with the Apple TB2 to TB3 adapter. USB 3.x docks and hubs often have a captive cable (cannot be removed without breaking something) with a USB-C jack or a micro-USB-B receptacle. The dock must have a USB-C port, a female receptacle, and not a USB-C jack, a male connector, for this to work.

I've seen people report that a TB3 dock will support USB 3.x (USB 3.0, 3.1, and 3.2) devices when the dock is connected by a TB2 adapter and cable. The TB2 to TB3 adapter does not support the USB protocol and does not provide power. The Apple Thunderbolt 2 to Thunderbolt 3 adapter will connect to USB-C hubs, docks, and devices with a USB-C port and supports the Thunderbolt protocol. Don't confuse USB-C the port with USB 3.0 the protocol.
