I've had a similar problems with a digital camera when permissions
weren't set correctly, but it's probably unrelated to this.

I suppose the first thing to check re: usb1 vs usb2 on Dell hardware
would be whether the usb controller is actually picking up the device

An `lsusb` (with a -v if you're feeling game) will give you all the
necessary information about connected devices.

If it's not showing up in the list, it's probably hardware related. If
it is showing up, it might be some sort of permissions based thing, or
maybe some simple misconfiguration with cups that'll take you half an
hour to find but end up being a single misplaced character. :-)
I've done zero configuration of cups.
This is failing
sudo /etc/init.d/hpoj setup
so permissions unlikely (unless I'm missing something)

echo "stuff" >>/dev/usb/lp0
make the printer make noises and such.

Check to see what type of USB driver you're using under Linux too (uhci,
ohci, ehci) - try swapping them in and out and see whether that makes
some sort of difference, especially if it's a usb version compatibility

hmm, scary, this was a pain to get right for wireless mouse and keyboard. Ok I'll try it

Finally, it could be just a driver related thing, with the printer just
not wanting to play nice with the Linux USB stack/drivers. I take it
you've googled for others instances of this?

I've googled the world. :(

We can rule out hardware, I was premature in my damning of Dell. I just booted a long negelected default OS that came with the box and got the printer working inside about 10 minutes of driver installation time.

Kind regards,
