Open it up physically. That's the only way.

It can't. It can give you the manufacturer's ID and device ID. A
number of manufacturers, however, have reused the USB IDs for different
devices or different models of the same device. Sometimes a "lsusb -v"
would give you the model and version, but not always.
D-Link was famous for this. They used the same USB ID for four
different versions of the same USB-based wireless network adapter--each
with a different chipset and requiring a different driver.
Frustrating.
