"On OSX, you can go launch System Profiler and look for USB. If you have a High-Speed bus, that means USB 2.0.

Also, the speed is shown, here it's 480 Mb/sec, indicating USB 2.0

Also this may help:

$ ioreg -k IOUserClientClass | grep UserClientClass | grep USBDeviceUserClient | head -1 | sed -e 's/.* = //'
""IOUSBDeviceUserClientV2"""
