Yes, indeed. I didn't notice this in my setup because the old config
files used /dev/ttyS6 (which doesn't exist on my computer). But later
.conf files use /dev/ttyS0 which does lead to large delays when no
dc25/dc210 camera is attached. Can someone think of and implement a
quick check whether a dc25/dc210 camera is attached? In the meantime,
I'll comment out these backends from dll.conf.
