As have several Linux distros, however the problem we are trying to
solve is that those device filenames *change* when you reboot or
disconnect and reconnect the printer.  The *only* configuration that
can work is for 1 printer, but even then recent changes in the 2.6.x
kernels force you to change the device filename anyways...

So, no, we will not be adding support for raw device filenames, and
future versions of CUPS will be using libusb and/or the raw kernel
interface instead of the character devices, since the USB character
devices are not compatible with HPLIP and other USB multifunction
device drivers.
