Hi Barry 'n' Folks,
Your 'pooter' probably don't know nuffin' about cameras. It will need appropriate driver! The Scanner too will have it's exclusive drivers which will need to be loaded. Linux probably has a bunch of generics to take care of most printers.
Most modern cameras are nothing more (or less) than USB Mass Storage devices when plugged in to the machine, and they generally appear in USB view as such.
Also, most USB scanners just use the generic usbscanner driver, then the backend in SANE takes care of the rest.
Printers are just devices on the end of an lpt or usb port, cups (or magicfilter, ghostscript, etc...) has the drivers, the kernel has a generic driver for the port that you're connecting to, then cups has backends that can talk to those ports, and .ppd files that describe how to process the print job in to a format that the printer is going to be able to read.
Anyways - back to the issue of the USB camera that's not showing up when it's plugged in... Hmmm, sounds very odd to me, not seen that issue before (my camera appears as a USB mass storage device if I plug it in, but I generally just use the card slot on the laptop to read the SD card from the camera... Incidently, that also appears as a USB mass storage device ;). I do remember that without using hotplug there here several modules I needed to load in order to use USB MSD, but I can't for the life of me remember exactly what they where, there was a scsi module and the usbstorage module, as a minimum...
