Has anyone installed isochronous support in the ugen devices in the 1.5 
branch?  I see that it's in -current, but I run 1.5.2alpha.  (My goal 
is to run the 'vid' USB camera package -- see
http://members.home.net/housel/projects.htm for details.)

The -current ugen0 doesn't compile, and I'd rather not do the back-port 
myself if I can help it.
