This makes it sound as if it was connected by some method *other* than 
USB before. Can you confirm that you have only ever used USB to connect 
the printer, and not something else (Ethernet, SCSI, Centronics, 25-pin, 
etc)?

If you type lsusb | grep -A 3 InterfaceClass

do you see the device listed?

I'm not sure I understand this. USB and HPLIP are two different things.
USB is a physical plug-and-socket arangement; HPLIP is a piece of software.

A defective computer USB socket, cable, or printer USB socket seems likely.

OK, so your computer recognises the printer. And the printer is 
self-identifying correctly. So *something* is passing between the devices.

Can you try something else:

1. delete the printer (do this using the web CUPS interface on 
http://localhost:631/)

2. remove all versions of hplip

3. unplug the printer

4. power down

5. plug in the printer

6. power up

(instead of plugging in the printer while the system is running)
