PRS has old firmware (no epub upgrade)

I debugged the Device detection and this was the output:

Device possibly connected: PRS-500 Device Interface
Trying to open device... failed
Opening of the following devices failed
<calibre.devices.prs500.driver.PRS500 object at 0x02A6E030>
Traceback (most recent call last):

Error: Could not find libusb.


I googled libusb and it appears to be some sort of open source USB drivers but i figured i would ask here just in case i am missing something stupid
