The reason I thought the laptop had USB 2.0 ports was because I get very slow transfer rates. Also, at boot-up, I get a message that the device would work faster with USB 3.0. As far as I know, the BIOS and drivers are up to date. How do I resolve this issue?

NO!! You misunderstood. The USB device is 3.0. It's a WD My Book. I've tried other USB 3.0 devices with the same problem -- transfer speed ~12Mb/s which is slower than USB 1.0!!!. Either the wrong drivers are installed (Dell's diagnostics is worthless) or there is something wrong with my computer.

No ExpressCard slot = not USB 3.0 ports

Hello Nastypup,
The Inspiron 5520 was shipped with three USB 3.0 ports and one USB 3.0 port with power share. Hence it makes 4 USB 3.0 ports.
Please write back if you have any further queries.

Hello Nastypup,
Please run the Microsoft Fix it to Diagnose and fix the USB problems automatically and check how it goes.
