OK, several ways you might like to try:
* export the USB stick (and the camera, if possible) as VBDs from dom0
* export the devices using networked solutions (e.g. NFS / NBD for the storage 
devices, something else must be available for the scanner), as you would for 
multiple machines
* try the PCI virtualisation stuff in the stable tree and give the USB 
controller device to the domain for direct control
* try the USB virtualisation stuff in the unstable tree and give the domain 
control of the appropriate host USB ports

Cheers,
