What I do is build the kernel modules for the things I need (parallel printer, usb printer, digital camera)
into the kernel. That way the drivers are always available  and I avoid a few module loading issues. I can't
see the point of modules if you compile your own kernel. The printers are always connected so I don't think
hotplug is relevant at all. CUPS handles them. (I won't start talking about cups or I'll be here all day ;) 
As far as the kernel is concerned my digital camera is fat 32 usb flash memory just like an mp3 player, flash
memory stick, usb portable hard disk, whatever. They all end up as /dev/sda1 and I mount them with this line
in /etc/fstab

/dev/sda1 /mnt/mp3 auto defaults,user,noauto 0 0

gphoto has never done anything useful for me but YMMV
