yes.

If scanimage works xsane should work as well. If it doesn't there's 
probably something wrong with your backend installation, e.g. you may 
have two versions of sane-backends installed (one in /usr/lib/sane.d, 
another in /usr/local/lib/sane.d)

You don't need the device nodes. The backend should always use libusb, 
which doesn't need the device nodes. You can check what's going on by 
running 
SANE_DEBUG_SNAPSCAN=255 xsane

If you don't get any output try
SANE_DEBUG_DLL=255 xsane 
and check that the snapscan backend is loaded at all. If it isn't, 
check the dll.conf configuration file.
