Unfortunately, no. /dev/lp? are character devices intended to talk to
printers and printer-like devices only. cqcam talks directly to the
system's I/O ports and thus actually does require root permissions.
(Otherwise the ioperm() call fails.)
You could make the SUID binaries roughly equivalent, permissions-wise, to
what you had above:
chown root.qcam cqcam xcqcam
chmod 4710 cqcam xcqcam
That's pretty much what I have on my system.
