You want "dpkg --configure -a"
--all isn't valid. The man page has the details.

All that does is finish unpacking debs and execute pending scripts. If
things are in a state where modules aren't being loaded, then it may
not fix much of anything. But, it's going to at least get the system
back into a state where apt-get can be used to install additional

Check that the kernel has loaded the right modules. See the wiki page
above for details.

Once you get the correct device drivers loaded into the kernel,
restart cups via the /etc/init.d script. Cups is the printing system,
if it isn't starting, invoking commands that query it is premature.

Stuff under /proc is generally a file or directory, not a command to execute.

I'm not sure what autoprobe is in this context.

That suggests that cups isn't running. Ensure the kernel modules you
need are loaded, then try manually launching cups via the
/etc/init.d/cupsd (or whatever cups uses). You could check via netstat
-pn to see if it's running.

I'd start by ensuring that the appropriate modules are loaded by the
kernel. Once you get those loaded, I'd (re)start the cups daemon. If
that gets things into a saner state, then I'd probably go about
ensuring that the modules you identify get loaded on boot. Perhaps it
will be as simple as adding them to /etc/modules (one per line).

The relative merits of usb vs lp is lost on me but this should get you
on your way.
