If there was no additional output at step 4, please try the following:

(or some other number) should be printed outsudo hexdump -C /dev/<name>
(replacing If there was output at step 4, please let us know.
If there was no output on step 4, it may be a hardware problem or hardware compatibility issue. The CTH-470 is quite an old device, so I assume you bought it used? If so, did it come with a stylus and does the stylus look like the one in the image below? Bamboo tablets generally aren't compatible with pens from earlier or later generations, so it is important to make sure the one you are using is compatible.
Thank you for your reply. I tried method 1, and at first it looked like nothing was happening. Then I "fiddled" a bit with the pen, dragging it around a bit, pushing harder then softer and so on... and occasionally I would get a reading. I'm pasting the contents here, but now I'm suspecting a failing hardware or something like a broken/cold solder point or something. I'll try to find a Windows computer to test the tablet there.
EDIT: Yes, I bought it used and untested, but the pen looks exactly like the one in the photo (except that both tablet and pen are silver instead of black). And they both look absolutely fine, with no external signs of damage.

Apologies, this slipped through. So based on the kernel output above the pen does send events. But given that you said
Then I "fiddled" a bit with the pen, dragging it around a bit, pushing harder then softer and so on... and occasionally I would get a reading
This means the HW is broken. The events recorded here are the ones that come out of the kernel and the kernel does little but convert and forward them on (for extra piece of mind you can use hid-recorder which prints the events as they come in from the device with (virtually) no processing whatsoever. But that won't change the outcome much - if you don't get events here as soon as you touch the tablet you have a broken stylus or tablet device.
I just bought a CTH-470 to replace my old Intuos. The 470 is a Pen + Touch device. The touch panel works as intended. But the stylus does nothing at all. The "Wacom tablet finder" does correctly detect it as "Wacom Bamboo Pen & Touch", with all the expected devices - pad, pen stylus, pen eraser, finger touch. On the graphic tablet's settings page, I can see no obvious way to enable or disable the stylus. On the "touch" tab there is a button to enable or disable touch, and this works - if I uncheck it, the touch is disabled, but then the tablet does nothing at all.
